I don't understand to what extent bots impacted Twitter's revenue or if at all that happened, after all, that only came up as one of a few tactics Elon tried using to get out of buying Twitter.

Thing is, as a public company, Twitter's revenues were public, amounting to $5.229B/yr (i.e., up to the sale). And, the New York Times reported they were doing $114M/quarter in early 2024. Annualized, that's $456M per year. So, an 87% revenue decline if we compare X's self-reported revenues against Twitter's last public disclosures before being acquired.
