Going from a model where social media is a new instance of the public square I guess I would agree there is no expectation of privacy in the public square, but where the public square metaphor breaks down is that this square is actually owned by a corporation that is taking pictures and wiretapping all the individual conversations taking place in their square and selling the contents thereof to other corporations. Not just that. Also selling the ability to remote control boom mics and remote control telephoto cameras, so they can send you an advertisement based on what you were looking at.
