If that was the criteria I would also be comfortable! However, it is not; the FTC has taken action* against many entities smaller than Facebook, and in point of fact Facebook might actually be one of the biggest entities the FTC has taken action against (I don’t think this puts an upper bound on the size of entity the FTC will take on, my point is that it certainly doesn’t put a lower bound on it). * Not necessarily actions I would call “thumbscrews” like their current proposed penalties for Facebook, and mostly actions I think are appropriate, but it is still an indicator of who they’re willing to take action against.
