What does Musk stand to gain by tanking Twitter? I don't know. Nor do I know what he thought he might gain by buying it. His explanation -- that he wants to save free speech for all humanity -- sounds so delusional and self-important I took it as either insincere or narcissistic. Given his history I settled on narcissism.
I don't doubt that if Twitter fails Musk will blame lazy and disloyal employees (or former employees), sabotage, the "woke left," spineless advertisers, greedy bankers. He won't see fault in his own actions, ignorance, failure to plan or set a course for the company. He already blamed "activists" for scaring off advertisers.
