Sure. It was a reply to a (dismissive) question asking what's the worst a regulator could do... it wasn't necessarily meant to be a reflection of what's really happening.

The harm of (captured-)regulated monopolies is real, but we ought to save this argument for important targets like the Daughters Bell. I offered an admittedly far-fetched example of a possible harm from regulating FB, in the hopes that you could come up with a more plausible one. No such luck!
