There are a number of mistakes in your sentence above. 1. There's no such thing as a "viral nature of the GPL". That's a phrase coined by its opponents to confuse and mislead the audience. It's as nonsensical as 'intellectual property'. Viruses jump from one host to another by mere physical contact, after reproducing using the host's cellular infrastructure. The GPL doesn't do any such thing. It reproduces along with the host (a program licensed under it), and it is only passed on to descendants (derived works). A more fitting term would be 'the inherited nature of the GPL'. Although it's true that diseases can be inherited, inheritances are often welcome. 2. The phrase "choosing the copyright" does not make sense. Copyright is a legal monopoly granted through copyright law to induce the creation and publication of *more* creative works. By default, creative works would be available for anyone to use, modify and share if it wasn't for copyright law. Copyright law provides the incentive by granting a temporary copyright monopoly to the author, thereby delaying the general availability of the work for use, modification and sharing by anyone. In some jurisdictions, one can contribute a work to the public domain, thereby making it available to all for all these uses right away, rather than having to wait for the monopoly period to lapse. 3. I don't think you were talking about "choosing copyright over public domain", though. I guess you meant "choosing the license", i.e., choosing which permissions you're going to grant over the derived work that combines portions (or the entirety) of the GPLed work, any other works, and the results of your own creativity. The GPL doesn't stop you from granting whatever permissions you like to whomever you like over the results of your own creativity. But copyright law may stop you from granting some permissions over the works you based your combined work on. And the GPL only grants you permission to distribute the combined work if you grant the same permissions subject to the same conditions, i.e., if you don't deprive the recipients of the enjoyment of the permissions the author of the GPLed granted them over the work (modified or not), and that, if they choose to pass it on, they also do so (by force of copyright law) without depriving others from the enjoyment of these permissions. 4. If you could choose any terms you wanted for the combined work, you could deprive recipients from the permissions over the GPLed work that one of the co-authors meant them to have. You can't do that unilaterally, by force of copyright law. You have to negotiate with all the co-authors. But they have already granted you permission to distribute the work in certain ways. 5. If you could choose any terms you wanted for the combined work, you could grant recipients additional permissions over the GPLed work that would enable them to do 4. You can do that only for the portions for which you're the sole author. Otherwise, you could make room for other parties to take away from downstream recipients the freedoms that the co-authors of the work meant them to have. -- Alexandre Oliva http://www.lsd.ic.unicamp.br/~oliva/ Free Software Evangelist oliva@{lsd.ic.unicamp.br, gnu.org} FSFLA Board Member ¡Sé Libre! => http://www.fsfla.org/ Red Hat Compiler Engineer aoliva@{redhat.com, gcc.gnu.org} -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
