I don't see China or Russia being denied, who would have the most to gain. Once anyone from there bought a single free copy, they could make as many legal free copies as they wanted, for all their friends in the countries you listed. You do understand how Stallman's license works, I'm sure Dark Lord.
Irrelevant.
Stallman has no relationship with this project. as for the rest, reread the disclaimer. Anyone can be denied.
If any nation/state/group wanted any code, they can simply steal and reverse engineer it, whether proprietary, BSD license, or GPL. Your concerns have no basis in reality.
Though it's not explicitly stated in the license, the government can still exercise its power to restrict any technology if its dissemination poses a clear and present danger to US military integrity or national security.
As usual, Dark Lord caught you red-handed posting crud again...
