The possibility of other takeovers doesn’t need to factor into this. If Twitter’s share price is significantly below the price they can force Musk to buy the company at, then the board has an obligation to shareholders to force the sale, and will be sued by the shareholders if they don’t.
It’s going to be interesting to see if Musk can prove they are holding back data.
I think Twitter does have a danger here. Their <5% bots was always an estimate. You can know, not know, or not want to know. That last part is the danger.
If they’re actually holding back data they contractually agreed to provide, then they aren’t living up to their side of the contract and maybe he has a way out. That doesn’t seem to be the case though. There is no “provided Elon Musk can verify that bots are less than 5% of users” clause in the contract.
