In this point, it is the interest of the CEO, board and shareholders to collect a fat check and let Mr Musk burn down with Twitter. It’s Musk’s problem what to do with an unwilling owner issues.
What fat check is the CEO and board getting? They own virtually no shares, so it wouldn't be from Musk. And if a reluctant owner takes charge, they aren't writing a fat check or shaking on a golden parachute. The lot of them can only expect to be immediately terminated, but knowing Musk, he would likely take legal action against them and do his best to make them unhirable... so they would likely bail during legal proceedings.
