It was Musk’s plan to use the Twitter buyout to liquidate Tesla stock without tanking the Tesla share price, as well as circumventing SEC rules he’d normally have to follow for a stock sale like that. He never intended to purchase Twitter, hence the stupid excuse of the number of bots and spam accounts, which were common knowledge prior to his stock bid.
He’s achieved peak oligarch stupidity–he’s so far removed from day-to-day common-sense decisions that he has no grasp of how transparent his actions are.
