> Seems like this is putting the cart before the horse. Why should we care what Facebook can and can't afford? We don't owe them a business model. The point of this is to remit to the user the value that has been extracted from them. If Facebook cannot make money, i.e. contribute value, on top of that, then they are actually a drain on society surviving off negative externalities and should go.

How are you going to value what has been extracted from them, though? Facebook is in a better position to value it than anyone: they're selling it. What people are willing to pay them for it is literally its value. I don't really see how you can decide that the value of the data is greater than what Facebook is extracting from it. If it were, they'd be charging that much.
