The twitter board has already announced it intends to litigate this. And they are not after just the $1B fee. That might be what Mr. Musk had in mind when he mentioned he was lawyering up in a few tweets awhile back. Even though he waved due diligence, that might not clear twitter from having lied about the bot problem. I suspect this is going into months of litigation. Perhaps Twitter will be willing to accept a lower price. It might be what Musk is angling for.
