I'm sure I have a biased view, but i hear people care about privacy in the same way they care about leaving facebook. They would like to, in a purely theoretical manner, but they aren't willing to change anything about their life to get that effect. It seems like many people only care enough about privacy to click a button.

Sure some people actually remove facebook, but the overwhelming majority of people are voting that they prefer the services offered, even with the tradeoffs. Unfortunate, but seems likely to me.
