Now, the NSA can do whatever they want, because they're completely
A: outside of the USA
B: totally foreign SIGINT
This is correct but also wrong.
For example, one thing the NSA can't do now is simply get a court to order the company to bend over, hand over the data, and then stick a gag order on it so the company isn't allowed to even resist.
By moving it outside the company, yes the NSA is now free to target them without restraint, but they are also free to talk about any attacks, and they are free to actively resist the NSA.
then they would be *safer* here in the USA where the NSA is not allowed to spy on them, because it's
A: in the USA (FBI territory, right?)
B: whoever it is would need a warrant.
Which they can get, from a secret court, that rubber stamps warrants. And they can also broadly interpret various legislation (patriot act, etc) to grant them all sorts of priviledges to collect data without a warrant...
And again, if they have a warrant, with a silence gag on it, you cannot resist. In any other country, the NSA can attack you all they like - but you can defend yourself. They don't get to just order you around.
