2. How come Richard M. Stallman never really answered the question of "won't programmers [content creators in general] starve?" in the GNU Manifesto?
3. If you used open-content artwork, music, foley artist audio clips, and stock digital video in a game or indie movie, are these royalty-free by definition, or is there some mechanism by which the content creator can still specify that he or she deserves a certain percentage of your profits? How legally binding would this be if you agreed to it by downloading the open-content work?
Please feel free to discuss.
(Context: I'm trying to evaluate for myself whether licenses such as the GNU General Public License (GPL) are really more modern in their authors' thinking about IP than closed-content licenses.)
