Twitter isn't like SpaceX or Tesla: there aren't enormous government contracts, subsidies, or climate credits to prop up its finances. There is no plausible replacement for the advertising revenue his style of leadership is actively alienating, and there is a real risk that his strategy is exposing Twitter to enormous FTC sanctions given that they are already under a consent decree.
It is much more likely that he's deeply in over his head and floundering than it is that he has a master plan he can only execute by taking a blowtorch to Twitter's current business structure. How much worse does it have to get before that theory is validated?
