Re: Your data
The point is that NSA (and pretty much any other agency) can simply send a secret FISA warrant and seize all the data by themselves. They don't need to hack stuff within their borders, they already have the omnipresent power there. That's why lavabit shut down.
Same thing applies to CBP, they can simply dump all your HDD's contents for later "research" if they want to at customs. This is why I had to delete sensitive client data before traveling to the US; I'd be involuntarily breaking NDAs just by entering the US. Extra points as the CBP power was given by a judge during a pedophile case, so it gets the added "for the children" mantra used instead of going after "terrists".
