Sounds like Musk is trying to find a way to wriggle out of the deal. He needs to either follow through or just pay a penalty (the bigger, the better) to end it all. And maybe not try any shenanigans like this in the future.
Twitter has done a workmanlike job of not getting pushed around by the spin: "Elon revives deal!!" No, actually, he hoped he could reset the clock, add conditions, and weasel out.
