if they even remotely try it, I bet each country will have their own dns server and broken internet. this clearly show that How gradually, USOFA do not have any intention to keep internet open. so it would be wise to move away from them while we can. ( only sometimes, once in a while, why it seems that china is better ? )
They've been acting as though they had jurisdiction for a while; there have been tons of .com domains seized for non-US sites. This is just a confirmation of their position.
