Every person that uses any free site (and I mean any free site) must understand that it is not, in fact, free, and therefore the site owner is going to try to find some way to make money from your use of the site.

Now, if I were paying for the site, I'd feel differently. In effect, I would perhaps feel as though I had paid for privacy. Match.com users should feel that way (I suppose…although I've not ever used the site). But facebook isn't a pay per use site, so no one should complain.

As far as privacy concerns, that's always been very simple for me: If I don't want my mom, boss, spouse, offspring, friend, etc. to see something, I never, ever put it on a free site. NEVER. Perhaps it's a good thing what facebook is doing, because it is forcing people to understand how laxed about their own poor privacy they have been, and forcing people adjust their own behavior. But leaving facebook…come on. That's just “sky is falling” talk.
