I don't know why you're getting downvoted this much. You raise a very good point about the nature of morality in advertising. Most ads are designed to convince people to make a decision that is against their best economic interest. And just because facebook is really good at directly targeting people who are most likely to make such decisions doesn't make them particularly immoral. Just more talented at it. But fundamentally speaking, it's just like the scams we see advertised on TV shows with the dumbest audience. It just feels worse when the statement becomes "we've found that John Foobar it an idiot--go take advantage of him," rather than "people who watch the Kardashians tend to be idiots."
