Good luck with that. He tweeted, early on: "If our Twitter bid succeeds, we will defeat the spam bots or die trying!"

Then, when you conclude a definitive agreement without any provision for an "out" based on an issue that you've already acknowledged knowing about (and hoping to fix post-acq)-- you're kinda stuck with it.

I think the big issue is that with the movement in equities, it requires him to overpay for Twitter with Tesla stock that is much less valuable. Financing the deal got much harder for him.
