Leaders lead.
Leaders don't cave to shareholders and advertisers; they persuade those parties to get on-board with the larger vision/mission, and they hold fast to first principles when things get dicey.
Maybe Jack is a good person, but he's no leader.
Maybe Elon is a douche-canoe, but he knows what leadership is and how it manifests. 

 CEO’s are not dictators & boards get votes.

I wasn’t there, not passing judgement, don’t know what happened, but it is possible that the board was full of douche nozzles. It wouldn’t be the first board to be and it won’t be the last
