Re: Bound and gagged
PR spin or not, Sections 4.6 and 4.7 of the contract (https://www.sec.gov/Archives/edgar/data/1418091/000119312522120461/d310843dex21.htm) indicate agreement to the numbers presented unless they have a Materially Adverse Effect on the post merger entity. That is a very high bar in the Delaware Court of Chancery. To the best of my knowledge, they have found an MAE to justify a merger termination exactly once.
Wasn't part of Musk's stated argument to take over Twitter that he would fix the bot problem? That might show that he understood the scope of the bot issue before agreeing to the terms. His rush through through the process (https://www.bloomberg.com/news/articles/2022-04-26/twitter-takeover-was-brash-and-fast-with-musk-calling-the-shots?cmpid=BBD051322_MONEYSTUFF) might come back to haunt him in court.
Nobody knows whether Twitter would prevail in a court action. These things are never certain, but the contract is clearly in Twitter's favor. The numbers were presented and accepted. Not only would it be necessary to carry the argument on statistical validity but also on a significant and ongoing financial impairment that is material. Again, a high bar.
