The minute you step out the front door any concept of privacy is a myth.

That's not the issue, the issue is being spied on for profit. Posting something to Facebook is not the same as walking out your front door. if your neighbor isn't on your friends list they don't see your posts(if you've set it up that way).

Everyone's every movement is being tracked, yes, and for the sake of security it's probably a good thing BUT is it acceptable to do so for the purpose of separating you from the money in your wallet? In a sense that is exactly the opposite of security and if you're prone to being influenced it's dangerous.

improperly tracked users even after they logged out

It's a problem given that Facebook sells the data.
