Whether or not the tech companies have too much power does not sound like the most relevant question here. The lack of power of citizens of communicate privately is the more worrisome thing. And maybe some random person is right to say that all of his communications are not something to hide. It becomes something else if lawyers and journalists can't protect their communications. If the state cannot suffer that it is rather likely that it is engaging in dirty business that it wants to hide, as pretty much all of them are.
