> "if you have any national identity, that is against our nation's constitution and we cannot work together with you." Well, exactly it's "if you have any national identity, feel free to adopt ours and work together" ;) And yes, I should have said "strong copyleft". The thing is, even if GPL replaced "all derived works are GPL" with "all derived works must respect user's freedom", any derived work would have to be licensed so similarly to GPL to be barely distinguishable. Say, if GPL work A was incorporated into a free-but-not-GPL work B, you still wouldn't be able to incorporate B into proprietary software because of the A part, even if B developers don't mind. MPL/CDDL avoid "virality" only by being weak copyleft, which GPL is supposed to be not.
