The agreement have a massive out; yes it doesn't matter what Elon thinks about the bots but if his financier think bots are an issue he gets an out since Twitter for some reason let a financing clause in.
You mean Musk agreed to buy Twitter contingent on financing and now is trying to torpedo his own financing after he himself agreed to the sale? There's a lot of talk of fraud in the comments here, but to me _that_ sounds like fraud on Musk's part.
In any case, I guess we'll have to see if Musk's financing really gets pulled and if that really means Musk is off the hook.
