Twitter's board saying the company only has approx. 5% of fake/spam accounts has been publicly criticised in the tech press. I am sure none of us have any idea what Musk's intentions are for Twitter but if he bought Twitter and then was to try and sell services to 3rd party companies, these companies prices would be based on the size of the user database and if Musk tried to claim that the user database only has 5% of fake/spam accounts the 3rd party companies would doubt his claim due to the claims in the tech press that the size of the fake/spam accounts is a lot lot higher than 5% and thus they could argue for a reduced deal price or walk away which does not help Musk at all. Therefore to negate the claims in the tech press Musk must find out what the actual percentage of fake/spam twitter accounts there are and to do that he needs the data from Twitter which he has been requesting and of which Twitter has been refusing to give him.
