It might be someone who wants to go after people precisely like you.
Can't believe this could happen is Sweden. In some countries - maybe. But it always surprised me, how quick the men, just had acquired the power could find and address their opponents. This is probably because their opponents are people who were in power for decades, and they left too much of paper work. So what can we do with Snowden or without: may be only amend to the constitution: "And your mail can and will be read." (And anywhere several video cameras will be pointed at you, of course)

And answering my own question: I still believe that all companies making biggest social networks just want the money. Nothing personal.
