Interestingly, I have never met a developer who actually read and used the license to take that interpretation with the exception of one large company who used it for reference implementations.

      If I copy a BSD-licensed file into a GPL v3 project, Does the GPL v3 require that this particular BSD-license allow the file to have its license changed to the GPL in the mere course of copying the file?

      Eben Moglen says yes, and thinks the BSD-license only requires that the file was once licensed under that license and so this is possible. I.e. only the notice of the license (as mentioned in the license) not the actual permissions need be passed on (by what does "... is permitted provided that..." mean in this context?)

      Richard Fontana states no, and thinks the BSD-license does not permit this because the BSD-license only allows for new copyrighted elements to carry additional restrictions, not for new restrictions to be extended to elements merely used with the permission of the original author.

      I suspect that Fontana's points are more closely reflected in the official SFLC advice that licenses to BSD-licensed files only are done after substantial modification and hence is more likely to be correct as it fits with my lay interpretation of copyright law better. Furthermore after in-depth discussions with many individuals who license their works under BSD-like licenses, I have come to the conclusion that this is the correct answer.

Affero GPL is therefore a usage license.

    Since there is no copying involved when users of a service use that server-side software remotely, copyright does not get engaged at all. This means that copyleft doesn't get engaged either (since copyleft is based on copyright), and that means that the Affero GPL is not a copyleft license when it is applied to server-side software. Instead it is a EULA controlling *usage* of a work. This sits extremely badly alongside Eben's common statement that the GPL is not a usage license. That's true for the GPL, but the Affero GPL is precisely that, a usage license by definition.

However, from discussing this issue myself with a non-profit lawyer, my understanding is that if *you* are the one writing the code, you remain personally liable for any problems it has even if you are totally working in good faith, like if you unknowingly infringe a software patent (good licenses can limit these liabilities somewhat). So I think this document is misleading in that it can be read to imply forming a corporation would protect the *author* of the code, when it really at best protects those who participate in the organization (board members) and who do not contribute code. For example, if you contribute problematical code to Apache, the Apache board may not be liable personally (even if Apache organization assets may be at risk), but you still are. So, in short, my understanding is that forming a corporation does not protect the individual contributors significantly from liability for their own personal actions, only from the actions of others (and even then, only when they are unaware of them or not directing them to various degrees). Perhaps they can address that issue in a future release; either indicating I am mis-informed or indicating that what I say is true. This is a very essentially point for individual developers to understand. It is one reason for liability insurance (and maybe the free software world could benefit by a good liability insurance system?) I think this is an important issue to get right, because otherwise it tempts free software developers (like myself) to spend a lot of time (and money) pursuing corporate forms which in the end may not provide much protection anyway for your personal efforts (compared to say, putting assets in the name of your spouse or having professional liability insurance). There may be other good reasons to form or join a non-profit though, but individual liability protection for the developer may not be one of them.

  25. Dangerously misleading statement on registration by DragonWriter · · Score: 1
    FTFA:

    Projects sometimes ask us about registering their copyrights. You do not need to register in order to have a valid copyright. You do not need to register to enforce your copyright. However, registration can provide a project with better options and an increased ability to enforce its copyright license against violators.


    This is technically accurate but potentially dangerously misleading. For virtually all actual ways in which you are likely to want to enforce copyright, in the US at least, registration is a prerequisite for legal action.

    Also, section 2.5 on "Copyright enforcement" skips over a rather critical area for a legal issues primer: the law. It focusses on knowing the license and its terms, and knowing the facts. It doesn't discuss much at all about the law which is necessary to understand how licenses apply to the facts. Now, for one audience that the piece is directed to (lawyers), this may be okay, since presumably the step of researching the applicable law isn't something they need to be told about (but then again, neither "gathering the facts" nor "knowing the license" are things that they should need to be told about, either.) For the other stated audience (developers, risk managers, etc.), though, this is a rather important point, and its kind of odd that "A Legal Issues Primer for Open Source and Free Software Projects" would skip over most of the legal issues almost entirely in the section on copyright, and be dangerously misleading on the one point where it does discuss the legal issues as opposed to the terms of particular available licenses. The Copyright section reads more as a primer on and promotion of the GNU Licenses and the FSF as a resource on the GNU licenses than a legal issues primer.

    The rest of primer, OTOH, seems a bit more substantial.
