This sounds good, and it would be a fine goal. The problem is that the very-very short deadline contradicts any good reasons, and he handles the whole situation terribly. I don’t think that there is any competent developer, who didn’t resign, or started to search a new job after the past few weeks (except who are religiously blind Musk fans, and people on visas). Even if only half of the stories are true. I did quit jobs for way less.

The goals which you wrote can be achieved with far superior tools, which wouldn’t have alienated developers, whose skills are really-really valuable on the market. In such environment, as what Musk created, they are the first who will abandon the ship. They have every possibility to work in any kind of environments what they want.
