When a company gets “in play” for an acquisition, almost always it sells to someone- even if not the original buyer. Once the Board and management shift into sell mode, they can’t seem to go back. It’s entirely possible Elon wanted mostly to push Twitter into play, and will get he wanted (sale/management changeout) without actually having to buy and run it. If what you want is to see current Board and management replaced, putting a company in play and torpedo-ing your own deal is amway to do that.
