What if we just want to break up Facebook for our enjoyment? It's legal to do so and we can do it. I can't remember where I heard that argument. I think it was some tech CEO (or maybe all of them).

I think that attitude is the root of our current political morass. The primary motivation is the desire to hurt those that we dislike/view as The Other, and we'll happily bend any logic or principles it takes to justify it.
