I think, in both the cases, the prime motivation would be money, if at all.

Elon "pushing" innovation means zero for most sane employees unless paid handsomely and compensated for the loss of "life" (depends on what a person calls life, because I have colleagues who are happiest at the work place and make an effort to stay extra hours; w/o overtime).

So speaking generally, both Elon and this Saudi billionaire are similarly bad employers if they advocate and push for for such unhealthy work-life balance.
