Is Facebook abusing its dominance to prevent competition, allowing it to artificially inflate prices? This was a big argument against Microsoft in the 1990s - they prevented computer retailers selling computers with non-Microsoft operating systems. On that level, I'm hesitant to call Facebook a monopoly. However, looked at another way, Facebook is now too important to be a private company. It has access to so much data about so many people that the potential for abuse is huge. I wouldn't want to see them become a government owned entity, as the potential for abuse would be just as great (maybe greater) while innovation would inevitably slow down. But I would like to see a regulator that sits on Facebook's board, can review its source code and order changes. My dream would be for Facebook to be broken up and turned into a protocol. But it seems that ship has sailed.
