Honestly, I doubt it. Bankruptcy puts him under the very direct supervision of the kind of federal judge that does not fuck around. And network-effects businesses like Twitter can do pretty well even when being neglected. I think he might continue to use the spectre of bankruptcy to scare his staff; he clearly likes rule through fear to create a false sense of urgency. That leaves him with people who will do whatever he wants no matter what it means for Twitter's users or society at large, two things Twitter's previous workforce cared about.
