No despot ever has a vote whose outcome they don't know ahead of time.
I believe Musk wants to resign. It's not fun anymore. He wants to go back to Tesla and SpaceX which are having successes instead of Twitter where he's having an unending stream of failures.
@ErrataRob Resigning won't stop the hemorrhaging of money at Twitter though. Also, would the next CEO really be in charge? What if they determined that the changes Twitter needs to right itself run in the face of everything Elon's been saying and doing?
