I find it interesting that most people have never heard of the saying "If you are not paying for the service, you are the service."
However, there are too many fools out there, like
ZhangirDuyseke, who are so intoxicated by big media that they go by "if you don't have anything to hide - why bother" that it is frightening.
However, that phrase is being spoken the loudest in the US. At least that is the way I have perceived it so far. This bein said - he has a point as well. You cannot complain that this has been done while happily posting on social media for everyone to see.
Before you're asking - I have social media as well, but that is LinkedIn only - which only has my CV in order to easier apply for positions, etc. I have no Facebook, Twitter and what ever they are called though.
So yes, as mentioned by other people, privacy has nothing to do with having no info online, but rather how much and available to whom.
