Page 9/84 in the "whistleblower_disclosure.pdf" are about Elon Musk's claims of fake twitter accounts and bots. Good lord, this does not look pretty for Twitter.
He's complaining that Twitter isn't measuring what he wants it to measure, which doesn't help, because it isn't saying that Twitter is actually lying about its metrics (and, as noted, it's indirectly implying that Twitter isn't lying).
The way it's framed ("Twitter lied to Elon Musk about bots") makes me suspicious of the whistleblowers' motives here. I know he's some kind of legend around these parts but I've never heard of him, so I'm just going by what I've learned today. Seems like propaganda to me, intended to maximally damage twitter and/or curry favor with Musk.
("Argawal's reasoning might appear a bit circular since, by definition, mDAU is more or less Twitter's best approximation of the set of accounts that aren't bots. And Agrawal is not exactly trying to help readers understand the bait-and-switch nature of his answer." - page 13/84)
