There's a third explanation: He's a fairly bad businessman but Twitter was always expected to lose money, and the purpose of owning it is to use it as a cost center for massive political influence.
I'm not necessarily espousing this theory, I have no real evidence either way, but lots of billionaires buy media outlets so they can direct public sentiment. Twitter, managed correctly, could have been a pretty good way to do that, but even within that lens it has been managed very badly, so IDK
OP, why is suicide the only way to fail? Rape, murder, torture, those all receive passing scores?
