Update: And he even deleted the Tweet now!
I'm starting to really wonder about a tin-foil theory that he wants to kill Twitter and have it file bankruptcy, then he can somehow write-off his investment and discharge the bank loans. Maybe that is actually plan B since plan A (back out of the deal, keep the $8B from selling his Tesla stock) didn't work out the way he expected.
[Edit] - Seems I am referencing fake tweets, which is a relief.
