The GPL is not about attacking copyright. Stallman's goal is "free software". And only if every user has the de facto ability (access to sources) and legal right (license, no patent problems, etc) to use, modifiy, and redistribute programs free of charge software will be free. Therefore the virality. Therefore the concern about web services and patents in the GPL3. So while I disagree with the tool they use to achive this (copyright) and dispute the necessity of it, their goal is honourable.

>limited form of copyright [..] for movies and for books that are the result of substantial research.

What do you regard as "substantial research"?
