Facebook reportedly argues there's no 'expectation of privacy' on social media
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.So as always metaphors are a lousy way to reason, and quickly break down because once you are arguing that X is like Y you will end up hitting the limit of X being unlike Y anytime you try to deal with something complicated in regards to X.Hence regulation of a medium where everything lasts forever and can be looked up instantaneously from almost anywhere, and copied and repeated all over the world by anyone wanting to do so, should not follow the model of regulation for a medium where everything is ephemeral and while theoretically open to anyone in practice not so open because availability of space is a limiting factor on proximity and proximity is needed to take part.
