Survey Says GPLv3 Is Shunned 382

willdavid writes in to note a survey of open source developers conducted by Evans Data that indicates a real rift in the community over GPLv3. The survey was based on in-depth interviews with 380 open source developers and no estimated margin of error was given. "Just 6 percent of developers working with open-source software have adopted the new GNU General Public License version 3... Also, two-thirds say they will not adopt GPLv3 anytime in the next year, and 43 percent say they will never implement the new license. Almost twice as many would be less likely to join a project that uses GPLv3 than would be likely to join... [Evans Data's CEO said] 'Developers are confused and divided about [the restrictions GPLv3 imposes], with fairly equal numbers agreeing with the restrictions, disagreeing with them, or thinking they will be unenforceable.'"

    It is much easier for new projects to start out with GPLv3 than old projects to convert. Unless the committers transfer copyrights to a central body like in the case of the gnu tools and FSF, it is hard to move to another license if not bordering on impossible.

            Well, yes, if it is not currently licensed with the restrictions in the GPLv3 (but merely allows other people to relicense their own redistribution that way), it is inaccurate to describe it as a GPLv3 project. I mean, by your argument, every project under a GPLv3-compatible license (or, presumably, in the public domain like SQLite) should be counted as a GPLv3 project because someone could conceivably redistribute a derivative of it under the GPLv3 at some point in the future.

          One key clarification here: You can't change the license on a piece of code unless the license gives you permission to sub-license. Otherwise, only the copyright owner can change the license on a file from, say, GPLv2+ to GPLv3+. Someone else can come along and add some GPLv3+ code to the GPLv2+ file, and the result will only be distributable under GPLv3+ but this doesn't mean the original GPLv2+ code has been relicensed. If the GPLv3+ code is removed, then the result will again be distributable under

        Unless, of course, all the commits were "GPLv2 or later", in which case the project was effectively already under the GPLv3 from the moment it was released.

        Wrong. The "or later" does not mean that whatever the most recent version of the GPL has been published is the one that applies. It means someone wanting to copy / distribute / whatever the software is free to do so under the terms of the GPLv2, or any later version that they might prefer the terms of. If the GPLv4 came out next week and said "to distribute software under this license, you have to send RMS a case of beer", you could distribute "GPLv2 or later" software by either providing its source (the GPLv2/v3 option) or by sending RMS a case of beer. New versions of the GPL give you more choices in licensing "or later" code, they don't retroactively change the terms of the deal like some shady EULA.

        Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

      • LedgerSMB is GPL v2 or later. At the moment there is no plan to change this to V3 or later.

        Now, this means that if you fork LedgerSMB, you can decide to use the GPL v3 for your license if you can meet the terms of that license (which by my reading would require removing any dependency on BSD-licensed code since the additional permissions cannot be meaningfully removed in accordance with section 7 of the GPL v3). This probably means a major port from PostgreSQL, or at least the stored procedures, etc.
        • . . . if you can meet the terms of that license (which by my reading would require removing any dependency on BSD-licensed code since the additional permissions cannot be meaningfully removed in accordance with section 7 of the GPL v3)

          An important point, but if you re-read my original comment you'll notice that it does not apply to such cases, since not all the commits were GPLv2-or-later.

          • All of *our* code is GPL v2 or later.

            However, the GPL v3 requires that certain dependencies are under the a license which allows for "relicensing" under the terms of the GPL v3 (see section 7). It is in the dependency area that you would run into trouble.
      • It depends on how that "or later" clause was phrased. If it uses the standard FSF phrasing, then you can redistribute and modify under the terms of the GPLv3, but... you still don't have permission to relicense. Unless the authors change the license, it will always remain "GPLv2 or later". New code (including significant modifications) can be under GPLv3, but only the original authors can change the licensing of the original code.
    • Unless the committers transfer copyrights to a central body

      Not so fast. In some countries it is not possible for an artist/author to transfer or give away his copyright ownership. That may be allowed in some countries but it is not an universal thing. Free software, on the other hand, is and therefore every project must take in consideration the laws which each developer is bounded to.

The primary difference between the licenses is how they treat changes or additions made to the original code. BSD doesn't require new work to be licensed under it and the GPL does.

        The "or later" clause only makes sense if the "or later" version is _less_ restrictive, in which case a distributor can point to that clause and the newer, less restrictive version of the GPL as a defense if accused of copyright infringement.

        No, the "or later" is important regardless of whether later versions are more or less restrictive. If a piece of code is distributed under "GPL version 2 or, at your option, any later version", you can use parts of it in your own program that you distribute under GPL version 3 or later. You could not do this if the code you wanted to use was licensed under GPL version 2 only.

    You mean the GPL3 is the Microsoft Vista of the open source licensing world?
  • All things GNU are going GPLv3, as is Samba. That's a pretty big and influential body of code, and it hasn't been established under the new license for very long. I'd give it time and I think you'll find version 2 will become more of a minority license. It could take years, and it will never be 100%, but I'd hardly call it a rift.

    The basic problem with this article is that it confuses Open Source with Free Software. They probably polled BSD, MSPL, Mozilla, etc developers and asked if they were planning to switch to the GPLv3, and as would be expected, most said "no". To me, it's just the obvious restated as something insightful.

  • 43% will never use GPLv3. How does this compare to the number who will never use GPLv2 either (ie, the BSD folks)?

    23% might use GPLv3, but not this year. Because there's really no reason to rush and/or the "improvement" might just not be worth the hassle of relicensing.

    Using GPLv3 scares away twice as many people as it attracts. Using it instead of what? If this wasn't specified then people are probably comparing it to their "normal" license, in which case BSD people will be scared away and GPL people

      We might get some numbers from SourceForge:

      There are currently 105950 [sourceforge.net] projects registered.
      Of those, 68143 are using the GPL and 11979 are using the LGPL, for a total of 80122 projects.
      The remaining 25828 use different licenses, which I am too bored to break down.

      43% of 105950 projects is 45558.

      If we assume that only people who currently use the GPL (and not LGPL) will consider GPLv3, then o
  • What's the difference between soup and gravy? That's the question that comes to mind whenever I hear someone trying to describe the difference between open source and free. There's a lot of fud, flame, and passion out there and its very confusing for most people. Most people just want shit that works.
  • In a survey of 1 Slashdot user, 100% of the users were found to think Evans Data are idiots for asking Open Source developers if they plan to switch to a Free Software license.

    Once adoption of version 3 slows, they'll just release version 3.5 and we'll all have to buy new books anyway.

The truth of a proposition has nothing to do with its credibility. And vice versa.
