I believe the breakdown is where private vs public vs "only my friends" If you were chatting with your friends at dinner in your home, there's no reason you'd assume that was public. Most people mistake Facebook for that when it's closer to chatting with your friends in a crowded subway car. In the real world, we'd see the difference, understand the difference, and likely decide certain topics out of bounds. Facebook's entire business is getting people to open up to advertise to them better so it's their best interest to make us think it's the dinner scenario.
