Elon or SpaceX? It's important to separate the person and their actions and the company. I wouldn't be surprised / hope that long term Musk leaves or is ousted from SpaceX entirely.
The actual reason why the two aren't comparable is that Elon is not just the CEO, but also a significant owner of SpaceX (42% equity; 79% voting control, according to Wikipedia). Tim Cook owns less than 1% of Apple.
