I really don't respect Mark Zuckerberg as a man, but it's hard to claim he's on the wrong side of history when he's the one writing a lot of it. To be on the wrong side of history you have to lose, it's not enough just to be morally wrong.
Good point. Nietzche pointed this out in Genealogy of Morals and Beyond Good and Evil. A lot of what we often think of as good and evil is just the preferences of whatever group happens to be culturally dominant at the moment, and Zuckerberg and co. is nothing if not culturally dominant right now.
