Boo Hoo!
I spent massive amounts of time voluntarily gving masses of data about myself to a commercial company, and they let other people access that data as it was now theirs according to their terms and conditions of use, and now I don't like what someone did with my data that I gave them, and I feel let down because I'd been told that it was the cool thing to do and I'd be left out if I didn't do it because everybody else was doing it!
What did you think they were, some sort of philanthropic idealistic charity? Could you not forsee any potential downsides to publishing everything about yourself online? Apparently the answer to such questions for most people is "yes". A fool and his money are easily parted. Now we know that a fool and his information are even more easily parted. And the fool can be easily be manipulated as a result.
