I agree with you in the long term, but in the short term, it will be quite the opposite, given the level of control his platform currently enjoys.
I blame most of Facebook’s missteps on the aggregate decisions of many FB employees that have less conviction on free speech than he does.
No company the size of Facebook could achieve a perfect response in real-time. Facebook’s greatest challenge is being headquartered in a place that is an ideological echo chamber chamber with not enough diversity of thought politically.
I personally don't like the guy, but believe me, there are a ton of people that assume his success is a sign of him being good and righteous.
As soon as he was entering the political spotlight, the answer is almost always no-one.
