The issue at it's most fundamental level is that people are putting things on Facebook (and other social networks) with an expectation of privacy in the first place. If you post something on Facebook, you have in fact decided that you do not have something to hide. I care about my privacy, but everything I've put on Facebook is public as far as I'm concerned. I don't care that they are using that information to profile me and serve ads for things I might like because I posted there with full knowledge of that. If I want something to be private, I don't put it on Facebook (or other social networks).
