Isn't this setting up a bizarre incentive where every time each of the entities feels it isn't getting it's fair share of Elon's attention, that they have to bribe him with some massive stock grant?
Why not? Eventually they would end up paying him just a bit less than the value he provides, which is what you'd expect from any fair employment agreement. At some point it would be cheaper to let him go or let him not try very hard.
