>Now that he's potentially not manic at the moment (possibly, I'm not his doctor) he realizes that he's not going to put an additional cent into it because the business can't be saved.
Frankly I'm still confused how his lawyers wrote the deal to buy Twitter the way he wanted to. He basically made it impossible for himself to back out, or even to have time to do due diligence. Why? The only thing I can guess is he was absolutely sure they would refuse the deal and would give some other concession, like a bigger board seat? Even so why didn't his own lawyers stop him?
