Which is great, if you have a decent idea of the NSA's (and the US intelligence establishment in general) capabilities. If not, you're essentially fumbling around in the dark trying to make that kind of infrastructure selection. (And, of course, the US intelligence community isn't the only threat, China -- through whom much traffic that neither originates in nor terminates in China is routed -- has to be a consideration, particularly, but they aren't the only other threat, either.)

If you don't have a system where you have strong theoretical guarantees of end-to-end security and integrity with the data sent over untrusted infrastructure, its security against any of the major threats really relies more than anything on them just not caring about it, and if you think that you are meaningfully buying security by choosing between Google or one of their competitors for basic services, you are probably deluding yourself.
