I'm a fan of Musk and his companies. I own one of his cars (as far as they can be called "his," obviously there are tons of people involved) and it's even better than all the "best car in the world!" people say. I follow every SpaceX launch and am eager to see them pull off their stage recovery attempts soon.
That said, this doesn't surprise me at all. He doesn't seem like the kind of guy I'd want to work for. My admiration is about vision and execution, not personal relationships. He may well be a dick, and it would be no shock if he is.
Maybe this is what it takes to do big things. Maybe it's entirely unnecessary. Either way it reminds me a bit of Steve Jobs, who was undeniably a massive jerk, but who got things done.
I forget exactly what my point was here. I guess it's just that this is a bit of a "water is wet" story mixed in with celebrity gossip. It's highly important for the people involved but not terribly relevant for the rest of us.
