One of the great things about tech culture is that management can’t just openly dominate engineers. “Because I told you so” is not an answer that engineers will accept. If you treat engineers this way (without world-class compensation) then they will just leave.
My guess is that a lot of founders are rooting for Elon here. To them, “because I said so” is a perfectly valid reason to do what I say, because, well, I’m the boss. Who are they to question me? Who are they to complain?
I sincerely hope that Elon fails, if only to temper the egos of would-be petty tyrants everywhere.
EDIT: I realized that it is uncharitable of me to wish for failure. I don't wish ill on any of Twitter's employees. I'll restate it: I hope that Elon is forced to reverse course on his management style.
