Free Software, Free Labor, and the Freelancer – WordCamp NYC 2014 keynote

I was honored to present the keynote address at this year’s WordCamp New York. Below is a rough copy of the text with some of the slides interspersed. (“Rough” means cobbled together from my notes, and minus most of the ***hilarious*** jokes. I guess you had to be there.) The video will be up on wordpress.tv within a few weeks.

===

The title of my talk today is “Free Software, Free Labor, and the Freelancer”. I’ve been asked to give this particular talk because I’m a freelancer who devotes large amounts of free labor to free software projects. The gist of my argument is going to be that freelancers can and should contribute more than they do, and I’m going to make this argument in a way that is sensitive to the economic concerns that are particular to freelancers and small business owners. I’m a developer, so most of what I’ll say will be specific to people who write code; there’s a lot to be said about the imbalances between coders and non-coders in a project like WordPress, but that’s a subject for another talk.

I’d like to start off by asking what it means when we say that WordPress is “free”. Many of the people in this room could rattle off, in their sleep, the two senses of the English word “free” when it comes to free software. What’s less often noticed is how these two senses can be at odds with each other. Let’s spell that out a bit.

The first sense in which WordPress is free is “free as in free beer”. When I invite you to my dorm room for a free Blatz, what I mean is that I’m not going to ask you for the 50 cents to recoup my initial outlay. “Free beer” is beer that you don’t have to pay for. And WordPress itself is free in this sense, because, in contrast to software like, say, Microsoft Windows, you don’t have to pay anyone to download or use the software.

But this is, of course, a secondary sense of “free”. When we think of WordPress as free software, what we really mean is “free as in freedom”. In technical terms, this means that WordPress is released under a free software license – in our case, the GNU General Public License, or GPL. The terms of the GPL can be summarized by the four essential freedoms that they guarantee to users of the software: (0) the freedom to use the software for any purpose; (1) the freedom to study and modify the software as they’d wish (this is the “open source” part); (2) the freedom to redistribute the original software; and (3) the freedom to distribute any modifications to the software. The GPL guarantees that users have these freedoms with respect to WordPress, and this is the primary sense in which WordPress is “free”.

gorges - wcnyc2014.008

The point I want to make at the moment is that these two senses of the word “free” are, in some sense, in conflict with each other with respect to software like WordPress. The root of the conflict is that building software – especially good software – is hard: programming is hard, design is hard, documentation is hard, support is hard, community building is hard. The fact that these things are hard mean that it takes a lot of people and a lot of time to build software. And this means, in turn, that it costs a lot of money to build software.

The traditional strategy for addressing this problem is to make your software proprietary. If you charge a couple hundred million people $100 each to use your software, you’ll have a few billion dollars that you can use to pay an army of programmers, designers, etc to build and maintain that software. But, prima facie, it’s tricky to keep this system up and running – the money only keeps rolling in if people are forced to pay in order to use the software, but software is by its very nature the kind of thing that can be infinitely copied and sent around the internet. The creators of proprietary software combat this problem by locking down their tools in a couple of ways. They lock it down in a legal sense, by requiring you to agree to End User License Agreements and other mumbo jumbo before using. They lock it down in a technical sense, through the use of license keys, DRM, and the like. And they lock it down through propaganda, such as the convention of using the word “piracy” to describe something that, in fact, is quite different from stabbing someone with a cutlass to plunder their dubloons.

By definition – remember the four freedoms – free software cannot be locked down in these ways. People can use it in any way they want (no contracts limiting use). People can distribute it in any way they want (no technical barriers to distribution). And the license actually encourages this redistribution (a fortiori, no moralistic jingoes about “piracy”, etc). At a glance, this breaks the economic model for creating and maintaining free software.

One of my heroes, Dolly Parton, has famously said about herself that “it costs a lot of money to look this cheap”. We can borrow this phrase as a slogan for the problem I’ve just described: “It costs a lot of money to be this free.” So that’s a problem that stands in need of some explanation. Given that it costs a lot of money to create free software, where is the money coming from? Who is footing the bill for WordPress?

gorges - wcnyc2014.016

The first group that comes to mind is what I call “the hobbyists”. This is Matt Mullenweg in 2004. Matt is one of the co-founders of WordPress, and the story of WordPress’s founding is, I think, typical of the story of the hobbyist free software contributor. Matt was a user of the free blogging tool b2. He and Mike Little decided in 2003 that they wanted to fork the tool to add some more features and make it a better fit for their own use cases. And they decided that their changes would be actively made available to a larger community. They weren’t getting paid for this – it was something they did for fun, to scratch their own itch. This kind of hobbyist is effectively donating his own labor to the project. And this is part of the story of who funds projects like WordPress.

gorges - wcnyc2014.017

The second class of folks responsible for funding free software is the business owners who donate some of their employees’ time to the projects. This is Matt Mullenweg in 2013. By this point in the history of WordPress, Matt is a successful businessman. Through Automattic (the company that runs the commercial wordpress.com) and Audrey Capital (his venture capital firm), Matt donates large amounts of employee time to the WordPress project. And Matt is only the most notable of a growing group of businesses that are doing something similar: a number of WordPress-focused web development agencies, webhosts, and other companies are following suit. So that’s another part of the story of who’s paying for free software.

It’s worth noting that so far I’ve described two groups of people on opposite ends of a spectrum: the hobbyist who donates time to the project for pleasure, and the employee who contributes because it’s part of his job duties. What about the rest of the spectrum? Well, that’s made up largely of freelancers. Unlike the employee, it actually costs the freelancer money when she contributes to free software, in the form of time not spent on client work. And unlike the hobbyist, the freelancer spends most of her day working with WordPress, which makes her very good at WordPress, but also makes her pretty sick of WordPress. So, at the end of the day, it’s likely that the freelancer would rather do just about anything other than, say, write a patch to submit to WordPress Trac.

This is the freelancer’s dilemma: she has the skills, and probably the desire, to contribute. But there are direct disincentives – financial and otherwise – to doing so.

In a few minutes, I’ll spend some time talking about strategies for overcoming this dilemma. But first I’d like to dispose of a common excuse that the freelancer makes for not contributing: Someone Else Will Do It. And of course, this is true – WordPress is a large project, and it’s in no danger of not being maintained. But a closer look at who that “someone else” is makes it clear that the freelancer is, to some extent, shooting herself in the foot by leaving all the work up to others.

gorges - wcnyc2014.022

To test this, I analyzed all the changesets that made up WordPress 3.9. For each changeset, I identified the “responsible parties” – those who had received “props”, or barring that, those who had committed the patch. Once I had these counts, I researched the employment situation of each contributor, and sorted them into various employer types. [I’ll try to write up the method and results in more detail in a future post.] Now, there are many reasons why you should take this analysis with a big grain of salt. But it does gesture toward some important patterns. The freelancer represents 238 out of 1380 commits during the 3.9 cycle. And about a third of those freelancer commits belong to a single person (Sergey Biryukov).

This seems out of whack. I don’t criticize Matt Mullenweg and his generous counterparts for funding the lion’s share of this work – I commend them for it. But from the freelancer’s point of view, it’s worth taking a closer look at exactly where the largest chunks of contribution are coming from, and looking in particular at the relationship between those contributors and WordPress. Andrew Nacin is a big portion of the yellow wedge here. He spends his days working on WP core, as well as maintaining the wordpress.org infrastructure (and a handful of other very unusual WP-based sites). The folks from Automattic are focused on wordpress.com, a huge and hugely influential WordPress network, but an idiosyncratic one in a number of technical and conceptual ways. And people in larger WP agencies as well as the Corporate category are working disproportionately on fairly large, high-traffic sites, largely for big media companies. But my impression is that these sites do not really represent what makes up the bulk of the WordPress sites in the world, most of which are fairly small and low-traffic – the kinds that are typically built by freelancers. There are specific considerations that are important for building sites of any type, and the people who build sites of that type are best positioned to ensure that the WordPress software is a good tool for building those sites. If freelancers want to ensure that WP continues to be the right tool for them and for their specific use cases – and they should – then they ought to be getting involved.

So let’s talk about some concrete strategies that the freelancer can use to contribute without doing undue damage to her bottom line.
gorges - wcnyc2014.027

The first strategy I want to discuss is what I call “patronage”. This is Mozart. Like many musicians and other artists before him, his art was financially supported (at least in part) by rich aristocrats. This was a time when there were fewer ways to make a living from the masses (no CD stores, for example), so one of the only ways for artists to get by was to find a person with deep enough pockets to fund the art. This worked out pretty well, at least in some cases: Mozart got to write music and put a roof over his head, the patron got the prestige of the commissioned works, and posterity got the benefit of Mozart’s music.

Free software patronage works in a similar way. Here’s an example. I wrote a plugin called BuddyPress Docs for a project at the City University of New York called the CUNY Academic Commons. They wanted a way for users to edit documents collaboratively, a sort of hybrid of Google Docs and a wiki, from within BuddyPress. It was clear from the beginning that this was a tool that lots of other BuddyPress installations could use too. I was very fortunate to be working with Matt Gold at CUNY, who has a deep understanding of the broader benefits of free software. So we agreed early on that the plugin would be made available on the wordpress.org plugin repository, and that the CUNY Academic Commons would pay me for at least some of the necessary upkeep on the public plugin. In exchange, the CUNY Academic Commons gets some good publicity. They’re listed as a plugin author. The plugin has been downloaded some 78,000 times, which sounds good when they are writing reports to their funders. And since the plugin was originally written for CUNY in 2011, I’ve parlayed it into a number of other patronage arrangements, with the University of Missouri and the University of Florida each requesting custom functionality which we arranged to have rolled into the publicly available plugin.

When it works, the patronage model is perhaps the ideal way to do free software development. Remember: our original dilemma was that time spent writing free software was time not spent doing client work. But when you’re working on patronage, you’re doing both at the same time.

But it’s hard to get patronage right. First and foremost, you have to find the right client. They’ve gotta be open-minded – and, ideally, excited – about the prospect of giving away a product that they’re paying for. And in most cases, that product is going to cost them more than it would cost them if it were not intended for general use – as any plugin or theme developer knows, creating something meant to be distributed is a good deal more complex and abstract than something meant for a single client site. Certain types of clients will be more naturally amenable to this sort of thing than others. I work primarily with public universities, where it’s pretty easy to sell the idea of using public funds for work that will benefit a broader public. Your mileage may vary.

Just as important, patronage only works on the right kinds of projects. Freelance projects usually start with the client producing a monolithic list of requirements. Part of the freelancer’s art is to turn this list into a scope of work that both satisfies the client’s needs and contains discrete items that are appropriate for general release. One of your jobs as developer is to know what’s needed in the community at large, and to massage your contracts in order to extract standalone items that address these needs.

You also want to make sure that you only agree to patronage setups when you – and the client – are willing to be in it for the long haul. Releasing a plugin means that you have a certain responsibility for upkeep. Include at least some of this upkeep in your ongoing maintenance contract with the client. And make sure that you pick something that you personally will want to continue to work on down the road.

One last point to make about patronage is this: Dirty work is hard to sell to a potential patron. Everyone likes the idea of having their name attached to an exciting new plugin. Fixing arcane bugs in an upstream project isn’t nearly as sexy. Unless you’re a really smooth talker, patronage probably won’t fund more than a small portion of your free software work.

So that’s patronage. It’s great work if you can get it, but it’s hard to get it right.

A more broadly applicable strategy for freelancers is what I call “the reputation cycle”.

Let’s start with some arithmetic. Say you work 1000 billable hours per year, and charge an average of $100 per hour. This would give you a yearly income of $100,000. Now let’s say that one day your hourly rate went up to $125. What happens to this equation? Well, you have a few options. One is to make an extra 25 grand:

gorges - wcnyc2014.043

Another is to shoot for the same income, but to work less:

gorges - wcnyc2014.045

Or you can split the difference, working a bit less but making a bit more:

gorges - wcnyc2014.047

This is a fun math lesson, but now we have to go back and answer the question of how to make this happen. If you’re charging $100 per hour for client work, how do you get yourself to $125 so that you’ll be faced with the choices described above? The question of how to raise one’s rates is, of course, the Great Question of All Freelancers, and there’s much that could be said (and has been said) about it. But there are a few very simple tips that I can give for justifying higher rates: get better at what you do, and get your clients to believe that you are better at what you do.

gorges - wcnyc2014.050

So what does this have to do with my talk today? Well, it so happens that these two tried-and-true methods for justifying higher rates are also two of the primary benefits of contributing to free software projects:

gorges - wcnyc2014.051

Let’s talk about these two claims in turn. First: how does contributing to WordPress make you better at using WordPress? I’d hope that this is self-evident at least to an extent, but it’ll be helpful to say at least a few words about the specifics.

Consider code review. hen you submit a patch to WordPress, it’s usually reviewed and commented on by a number of committers, and probably multiple other seasoned contributors. How much would it cost if you had to pay for this kind of professional code review? This point is especially important for the freelancer, who, by definition, works alone. The opportunity to learn new techniques and t get high-level feedback on your work is invaluable. And this kind of feedback is a free benefit of contributing to the project.

Another way that contributing can make you better at WordPress is that it forces you to learn more about WordPress. There is simply no better way to learn about how WP works than by diving deep into its very bowels. For every ticket you decide to adopt, you’re bound to find one feature of the software you never knew about; or learn one more odd quirk; or ideally, fix one problem that was bugging you. Over time, these little things add up: you’ll find yourself choosing better client implementations, making fewer mistakes, and getting your paid work done more efficiently.

There’s a lot more that could be said about how building free software improves your skills. But let’s change course for a moment. Remember, we’re trying here to suss out how contributing to free software can justify charging higher client rates. For that to happen, the client has to believe that you’re worth those rates. So let’s talk a bit about reputation.

Maybe the most direct benefit from contribution is that it gives potential clients independent verification that you are, in fact, an expert in your field. Put yourself in the place of a client who wants a WordPress website but doesn’t have the technical skills to tell apart self-proclaimed “experts”. Are you willing to pay a 10% or 20% premium for someone who can prove that they’ve written a popular plugin or even written a small part of WordPress itself?

gorges - wcnyc2014.060

Check out this page from the website of WordPress freelancer Bill Erickson. He’s listed details about his publicly available plugins, download counts, a list of WordPress-related presentations, patches accepted to Genesis and WordPress, and so on. I’m sure Bill lists this information here because he’s proud, and rightfully so. But it plays an equally important role in verifying his claim to be a WordPress expert.

Simply blogging about WordPress is another way to demonstrate your expertise in a concrete way – an especially effective one if you write a blog post that ranks high on Google. I’ve written technical posts about BuddyPress that still get Google traffic five years later. My rate for BuddyPress consultation (which makes up almost all my client work) today is almost 10 times what it was in 2009, when I started doing this work. What justifies that in the eyes of clients? There’s a lot to be said about that, but in part, it’s things like:

Each of these is an independent verification to clients that I am, indeed, the expert I claim to be. This stuff is hard to fake.

A less obvious way in which contribution can have ramifications on reputation is that it helps you tap into a network of quality referrals. Active participation in the WordPress community will get you noticed by other members of that community. And prominent members of the community are likely being solicited with very attractive job offers. Becoming a trusted member of the community taps you into this referral network. I personally send a few dozen referrals every month, and the people I send referrals to are exclusively those I know from the WordPress and BuddyPress community.

Let’s go back to the main point here. I’ve been talking about a strategy I call the Reputation Cycle. Here’s the “cycle” part of it.

gorges - wcnyc2014.067

When you contribute to free software, over time you will improve your skills and reputation. As a result, you’ll be able to demand higher rates from your client work. When that happens, you can work a bit less over the course of the year, and still make the same amount of money (or even more!). Some of that freed-up time can then be put back into your free software work. And the cycle begins again.

I think this is pretty compelling. But if you’re not convinced that this is a good thing for you personally, consider this: This kind of cycle is imperative for the future of WordPress and free software in general. Take another look at this chart I showed earlier:

gorges - wcnyc2014.022

One of the patterns it suggests is that a disproportionate part of funding for WordPress’s development comes from a fairly small number of sources: Automattic, Audrey Capital, 10up. When a freelancer spends an hour working on WordPress, it’s being paid for by the freelancer’s client (whether directly or indirectly). In this way, the freelancer converts a marginal amount of the money spent by clients on WordPress-based sites into a direct benefit for the WordPress free software project.

This is a form of redistribution. One way to think of it is that the freelancer is a kind of Robin Hood – taking from the rich to give to the poor. But I think this is a bit coarse, and prefer to think of it as a more subtle effect. Freelancers have the chance restore some equilibrium to the system, by shifting some of the onus of footing the bill for WP off of Matt Mullenweg and a few of his generous counterparts and onto a much broader subset of the WordPress universe. This dynamic ensures that the project is funded in a less centralized way, and helps to make the future of the software more secure.

gorges - wcnyc2014.070

One more thought to wrap things up. I’ve been freelancing full time for about four years. Over that time, I’ve used the techniques described today to get myself to a point where I spend about 50% of my working time doing non-paid free software work. I’ve chosen to orient my career this way because, like Richard Stallman, the father of the free software movement, I consider free software to be a critical tool in accomplishing some important moral and political goals that have implications beyond the software itself. But I’ve intentionally avoided framing today’s talk in this way. Nothing about how contributing is the “right” thing to do, or that you “owe” it to WordPress. If you are a freelancer who couldn’t care less about the GPL or user freedoms or Richard Stallman, my argument is that you still ought to contribute out of mere self-interest. And if you’re a freelancer who does care about these things, my argument is that there are strategies that help you to contribute without undue financial sacrifice. In my view it’s a brilliant structural feature of communities structured by the GPL that you don’t have to care about the ethical implications of free software in order to benefit from those implications. In other words, it’s equally valid to contribute for the sake of others or to contribute merely for yourself.

The GPL is for users

The General Public License (aka the GPL) is for users. This observation seems so obvious that it needn’t be stated. But for those who develop software licensed under the GPL (like WordPress and most related projects), it’s a fact that should be revisited every now and again, because it has all sorts of ramifications for the work we do.

Users versus developers

What do I mean when I say that the GPL is “about users”? Who are “users”? We might draw a parallel between software and books. Books have readers (hopefully!), and they have authors. Authors read too; proofing is a kind of reading, of course, and one might argue moreover that reading is an inextricable part of writing. Yet when we talk about a book’s “readers” we generally mean to discount its author. ‘Readers’ in this sense is a gloss for ‘just readers’, that is, those readers whose relationship to the book is limited to reading. The situation with software is more complex, but roughly the same distinction can be made between users and developers. ‘Developers’ refers broadly to those people involved in the conceptualization and implementation (and also often the use) of a piece of software, while ‘users’ refers to those who just use it.

My reading of the GPL is that it’s heavily focused on users. (References to the GPL throughout are to GPL 3.0. You can find older versions of the licence, such as version 2 that is shipped with WordPress, on GNU’s website.) Take the opening line from the second paragraph of the Preamble:

The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program–to make sure it remains free software for all its users.

Here as elsewhere in the text of the GPL, no real distinction is made between “you” as it refers to developers and “you” as it refers to users. Closer analysis makes it pretty clear, though. Take, for example, the freedoms that are purported to be taken away by proprietary licenses: the freedom to “share and change” software. Developers – or, to be more specific, license holders, who are generally either the developers themselves or, in the case of work for hire, the people who paid for the software to be developed – generally do not restrict their own rights to share and change the software that they create. Instead, restrictions are imposed on others, the (“just”) users.

Similar reasoning applies to the core freedoms that are outlined in the Free Software Definition, a sort of unofficial sister document of the GPL, also maintained by the Free Software Foundation. The four freedoms:

  • The freedom to run the program, for any purpose (freedom 0).
  • The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
  • The freedom to redistribute copies so you can help your neighbor (freedom 2).
  • The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

On the face of it, freedoms 1 and possibly 3 are focused on developers, in the sense of “those who are able to write code”. But, with respect to a piece of software that they did not write and whose license they do not control, coders are just regular users (in the same way that Vonnegut may have been a “reader” of Twain). All four freedoms, indeed, are user-centric. The license holder, almost by definition, doesn’t need permission to use the code (0); the developer doesn’t need to study the code to know how it works (1); owners can redistribute at will (2); owners can modify and redistribute at will (3). It’s only in the context of users – those who did not write the software – that these freedoms need protection in the form of free software licenses like the GPL.

The GPL does make a few explicit provisions for the developer/license holder:

For the developers’ and authors’ protection, the GPL clearly explains that there is no warranty for this free software. For both users’ and authors’ sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.

The second provision is a sort of legal convenience; the first intends to ease what may otherwise be a prohibitive consequence of the core freedoms guaranteed by the rest of the GPL. Both are important and valuable. But it seems fair to say that they are secondary to the user-focused parts of the document, at the very least because they are motivated by other parts of the document, while user freedom needs independent justification.

There’s no question that the people who bear the brunt of implementing and upholding the GPL are software developers. In that sense, the GPL is very much “for” them. But, in a broader sense, that’s a bit like saying that school is “for” the teachers because the teachers play a key role in education. Schools are for children; they provide the motivation and justification for the whole enterprise. Similarly, the GPL is for users; if everyone wrote their own software, and there were no “just users”, the GPL (or any free software licenses, or any licenses at all) would be unnecessary.

Sacrifice

If I buy a pizza, I trade ownership of money for ownership of pizza. Once I have the pie, I can do pretty much whatever I want with it. I can eat the whole thing myself, I can share with a friend or two, I can throw it on the sidewalk. I can save the pizza in hopes that prices rise so that I can make a quick buck in a resale, I can retail off the individual slices, or I can give the whole thing away. I can’t use the pizza to solve world hunger (not because I’m not allowed, but because it’s not possible); I can’t use the pizza as a deadly weapon (not because it’s impossible, but because I’m not allowed). In short, ownership bestows certain rights. Not all rights – I don’t have the right to murder with the pizza, or to do impossible things with it – but many, even most of them.

The situation is more complex with intangible goods; especially those, like software, which can be reproduced without cost or loss. Copyright law in the United States (so far as I understand it; IANAL etc), in accordance with the Berne Convention, grants rights over intellectual and creative works to the authors automatically, at the time of creation. Thus, if I write a piece of software (from scratch – set aside issues of derivative work for a moment), I am granted extensive rights over the use and reuse of that piece of software, automatically, in virtue of being the author. That includes copyright – literally, the rights related to the copying and distribution of the software. In short, the default situation, for better or for worse, is for the developer – and only the developer – to possess the rights and freedoms enumerated by the Free Software Definition. By default, nothing is protected for the users.

Free software licenses exist in order to counteract this default scenario. But keep in mind what that means: When a developer releases a work under a license like the GPL, certain freedoms and rights are granted to users, which necessarily restricts the freedoms of the developer. The GPL admits as much:

To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.

“Responsibilities” is a nice way of putting what is essentially the stripping of certain rights (in the same way that, once you become a parent and thus responsible for your child’s well-being, you no longer have the right to go on a week-long bender). Once the software is released under a GPL, the original author has lost the right of exclusive distribution of the original software. Subsequent developers, those who modify and redistribute the software, are similarly restricted.

It’s a trade-off. Users get certain rights (viewing source code, copying, modifying, redistributing) because the developers have given up the default right of exclusivity. Examined in itself (without reference to subsidiary benefits for the moment), the trade-off is clearly made for the benefit of the users, and involves sacrifice on behalf of the developer, sacrifice which is usually quantified in monetary terms (Bill Gates didn’t get rich by writing open source software), but could also be associated with pride in being the sole author, etc. There are, in addition to this, secondary sacrifices involved in free software development (loss of identification with the software because of modifications or forking, less guaranteed income than in a proprietary development shop, increased support requests that come from wider use of a free-as-in-beer product [though the GPL explictly says that you can charge what you want, and that no warranty is implied]). To some extent, these secondary sacrifices can be mitigated by the realities of the market, and are anyway subject to the particulars of the scenario in which you find yourself. But the core sacrifice – giving up exclusivity over distribution – cannot be separated from free software licenses.

Software licenses are political documents

Developers have all sorts of reasons for releasing software under free software licenses like the GPL. A few, off the top of my head:

  • You want to modify and redistribute existing software that is GPLed
  • You want to distribute somewhere that requires GPL-compatibility, like the wordpress.org plugin repository
  • You believe that forkability and other GPLy goodness makes for a better product
  • You want to develop for a platform, or contribute to a project, that requires GPL compatibility

I classify these reasons as prudential, in the sense that they are focused on the material benefits (money, fame, better software) that you believe will come from developing under the GPL. All of these reasons are great and important, and many of them have motivated my own work with GPL-licensed software. Taken together or even individually, it’s easy to imagine that these (and other) benefits would outweigh the sacrifice involved in giving up exclusive distribution rights over your work.

There’s another kind of justification for releasing under the GPL: you endorse, and want to advance, the political and moral ends that motived the creation of the GPL. The GPL assumes that it’s a good thing for users to have maximal freedom over their software:

If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

The assumption here is that “greatest possible use to the public”, and by the extension the good of the public, is something to be actively pursued – a moral claim par excellence.

And, among free software licenses, the GPL is perhaps the most explicit about the ways in which user freedoms (and thus the greatest good of the public) should be guaranteed and propagated. The “viral” nature of the GPL constitutes a kind of normative statement about the value of user rights over developer rights, which goes beyond other free software licenses that do not share its viral nature. The difference might be summed up like this. Alice and Bob are coders, and Carol is a potential user of the software. If Alice writes a piece of software and licenses it under a free software license like those in the BSD tradition, Bob can fork the software, make a few changes, and sell it to Carol under any terms he’d like – he can compile a binary executable for distribution, without making the source code available, converting his fork into closed-source, proprietary software. If Alice licenses the software under the GPL, on the other hand, Bob can still modify and sell to Carol, but he may not change the terms of the original license – in particular, the source code must be made available for further modification and distribution.

The normative aspect of the difference is in the value that each license scheme ascribes to the rights and freedoms of various individuals involved. BSD is more permissive with respect to Bob; GPL limits his ability to license the derivitive work as he pleases. GPL is more focused on Carol, and protecting her – and other “just users” like her – at the cost of some of Bob’s freedoms. (The GPL is for users.) One might express the difference in political terms thus: the GPL is more liberal, and less libertarian, than the BSD. Users, who are on the weak end of the power spectrum when it comes to software, are protected under the GPL, in the same way that society’s underprivileged and weak are often the focus of political liberalism. On this picture, licenses, like laws more generally, are designed in part to create the restrictions necessary to protect the positive freedoms of a vulnerable population.

For developers who agree independently with the normative principles underlying the GPL, its moral benefits can outweigh the sacrifices it entails. Such a justification is the starting point for Stallman and the Free Software Foundation (see, for example, the FSF’s about page). You may, of course, foreground other aspects of free/open-source software when justifying your licensing. I’ve listed some justifications above, and entire movements have sprouted to focus on prudential, rather than moral, justifications for open source development.

But – and here’s the rub – licensing your work under the GPL constitutes an endorsement of its moral justifications, even if it’s not (from a cognitive point of view) what motivated you personally to apply the license. If you choose a free software license for prudential reasons, you are not justified in complaining when your project is forked. If you choose the GPL for prudential reasons, you can’t altogether disavow the inherently altruistic underpinnings reflected in the license’s preamble. Put another way: Among other things, software licenses are political documents, and it’s incumbent upon developers to understand them before adopting them.

It’s important for developers to think carefully about this before diving into a license. My own take is that the original motivation for free software – that user control over the software they use is fundamental to their autonomy – becomes truer every day, as more and more of our agency is mediated through software. For that reason, licenses like the GPL are ethically important, at least if your worldview depends (as mine does) on respecting the agency of other human beings.

This post was prompted by a recent post by Ipstenu. Much of my thinking on the matter is clarified and inspired by the first few chapters of Decoding Liberation: The Promise of Free and Open Source Software, a book about free software written by philosophers/computer scientists Samir Chopra and Scott Dexter. You can (and should) buy the book here.
