Correct. The downside is merely the failure to provide even more incentive for the possibilities that are effectively explored to become something that everyone can use in as much freedom as the original. You can say as much as you like about the local optimization afforded by permissive licenses. The wish for power to take control away from others who fall in your trap can indeed cloud the judgement. Copyleft is about global optimization. It's about ensuring everyone who receives the software can be Free. Yes, there are unfortunate downsides because of license incompatibilities. This is not exclusive of copyleft licenses. We've also covered in fedora-devel that authors who want to cooperate to promote a better world will find a way to cooperate. > To understand why, have a look at >> http://www.lsd.ic.unicamp.br/~oliva/papers/free-software/BMind.pdf > Your scenarios have nothing to do with real-world possibilities. Indeed, they're very abstract.

Why bother with Free Open Standards, let's just copy the code, right? Nevermind that the kernel Linux wouldn't take code under the original BSD license, out of license incompatibility, and their TCP/IP stacks could (and still can) interoperate. So there... That implementation made life easier for all those OS vendors who didn't want to respect their customers' freedoms, but didn't help much other communities who did. -- 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-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
