I think the larger dependency is on the investors, not on employees. There seems to be quite a bit of support and good will from investors towards Musk. And this is understandable, no one wanted to see a failure to electrify vehicles. But taking money from Tesla and putting it into Twitter is bound to ruffle some investor's feathers. And bound to increase the attack surface (i.e. big automotive withdrawing advertisements from Twitter).

As to 'A' game, it is strange how often that everyone is so convinced that the 'A' game is being played. And yet there is very little market impact. And a lot of investors money is getting burned. While the 'long game' is paying all the bills.
