As an non American this annoys me immensely. US law basically states that non citizens have no right to privacy nor fair trials whatsoever (A foreiginer is not a person as defined in the constitution, this was the justification for why those in Guantanamo did not get a fair trial). So N.S.A basically admits that it's basically treating everyone else as fair game.
What can we, those not from the US, do to fight this? Naturally we cannot affect this by voting so how can we get Americans to change things? Add "Only for non US use" to any OpenSource projects we release?
But on a more serious note. Would you think it would be totally ok if other countries take similar stance towards US companies and persons? Perhaps most importantly for Americans all of this can potentially weaken the US negotiation position in copyright enforcement, and for a country that depends extremely heavily on IP it could be disastrous.
