You are omitting one relatively large detail. Did Twitter commit Fraud? Twitter's SEC filings, and statements given prior to the sale agreement mentioned that 95% mDAU; however several independent sources have shown that the number of bots on Twitter are well in excess of 5%. This is fraud on multiple levels, first and foremost, this is fraud that is actionable by the shareholders, who base the stock value upon the number of live interactions, then there is fraud by filing with the SEC, then there are advertisers who paid Twitter, based upon inflated numbers of potential customers they were promised to have access to; and finally, the stock price that Elon agreed to, was based upon accuracy in the disclosed information.
For example, if I agree to sell you my company and as part of the pre-sales negotiations show fraudulent earnings, properties that I do not own/lease, sales that did not happen, and buildings that have been condemned, without disclosure - I have committed fraud. You do not only have the opportunity to decline the sale; but can take actions against me for the fraud I committed, leading you to invest time and resources to unveil the deceit.
