Apple is a bad example, since it literally almost failed after they ousted Jobs... And yeah, Musk is one of very few who created major changes in several industries, and 7 billion people didn't. Removing Musk now, when Tesla is on a brink of becoming profitable can create an avalanche of bad things that will destroy it. I agree though, that tweet was very unfortunate, really doesn't seem like clever thing to do if you can't back it up.
