Legal experts: Can Musk really back out of the Twitter deal?

To the M&A legal experts on this board: given the specific performance clause, Twitter disclosure that DAUs are estimates (and could in fact be higher), and stated intent of Musk to clean up the bots on Twitter when he announced a pseudo hostile takeover, is it actually possible that he can walk away from this deal using bots as an excuse to avoid a the general tech valuation drop to secure a better deal? Or would a Delaware judge laugh in his face and force specific enforcement?

There is a large merger arb on this if he is in fact on the hook for $54.20 which seems highly likely. I'm wondering what hackernews legal experts think.
