Do they always have the option of settling at any point in the process? Like if Musk said "$20 billion penalty but I don't buy the company", I assume they'd say yes? (Or substitute a bigger number if not.) So are they just negotiating at this point if Musk has a penalty number he's willing to pay?
My bet is on this. They will just negotiate. Nobody wants to go through a lengthy legal process. I think the number will be at 5b. Because, at 5b, Twitter gets a 1y revenue for virtually no cost. Twitter doesn't want to sell to a buyer who doesn't actually want to buy. It's not good for anyone. Imagine Musk buying Twitter and starting open up exec emails knowing about the bot numbers being inaccurate.
There's different levels of knowing about inaccuracies.
There's knowing that your methods of determining bots are probably not optimal and the number is most likely undercounted, but it was a good faith albeit imperfect effort.
Then there's knowing that bots are actually some other specific number and suppressing that information.
I think the former is much, much more likely than the latter and wouldn't really be a huge controversy if it leaked.
