> he's Elon Musk and he doesn't care about investor returns

Then he shouldn't be the CEO of a public company which continues to sell stock and debt to investors on the promise of a return.

Also, Elon Musk very much does care about returns. He has a great track record in that department. He's just learned it's not something that's healthy to focus on in the short-term. Unfortunately, running out of cash forces the compression of time horizons. The latter is what investors are rightfully worried about.
