"these countries (except for cuba, that i don't know what the US wants from) are dangerouse, open source or not. we have some personal knowledge about it."
The ruling governments are, to different extends, not every citizen. Don't you people know that the only way to maintain a dictature is to keep people uneducated and uninformed? That preventing the means of aceess to information to get there is encouraging these regimes? One thing is for sure, your government sure does understand that. Most importantly, the U.S. governement is so much more dangerous than all of those combined. "and other U.S. law" Fuck your laws, once this leaves the contry, it is no longer subject to U.S. control. Well, if only that was true, but since my government is a serf, it probably isn't anymore... "And the developers? Shall they and their families move, too?" Yeah, so all the developers are USians? That's typical USian arogance. Why should contributed code by subject to those rules? As I understand it, it's only the crypto parts that's covered by those laws. You could at least bother distributing non-crypto builds and source so they can get Mozilla and use a PGP plugin from non-us sources or something.
