There is one huge reason why this isn't as scary as it could be:

Tabloids.

If you read through the Tabloids, there is no doubt that some of the stuff in there is slightly true. But you, as the reader, have really no way of knowing what is true or not. So just the fact you have all this information really puts you in the same position of not having any information--not knowing what to believe is almost as bad a problem as not knowing at all. So you are really forced to ignore most of it.

Now, the NSA can read everything you say/write/browse/whatever. Ok, well, what about the people who know that someone is listening so they intentionally create fake stories? Part of being a good criminal or anything is misdirection. Maybe you portray over email (for, get this, years) that you have hideouts at x, and you are good at y technology, and you associate with z people---but in reality you only ever say meaningful stuff in person. Anyone doing anything actually wrong is doing this anyways. That's why there are private code languages in the first place.

So, no, the power is not in the hands of who can listen, it's in the hands of who can deceive--which is you.
