Honestly, I think they'd be happier too. They'd have less money and power, sure, but they'd also get less death threats, and a lot of the world (including world leaders) would hate them a little less.

I don't think they would care if Facebook and Twitter were each 1/10 the size of what they are today -- they'd still be billionaires and the companies would still be mind-boggling huge. They only care that the companies are much larger than competitors.
