The two twitter exec firings yesterday must be related to this. Musk must have asked for proof which the product team could not produce.
Misrepresenting spam/bot accounts would fall under that bucket. If the number of spam accounts is like 20% (instead of 5%), not only would the deal fall through, other shareholders would sue twitter.
Not sure this misrepresentation would count as financial misrepresentation (which results in jail etc under Sarbanes-Oxley)
If he's on paternity leave he won't have been responsible for a number that came out last week.
That's assuming the firings are fully rational, and no self-interest was involved.
I can easily imagine a number of scenarios where Parag fired the guy knowing he had done nothing wrong in order to attempt to protect himself in some way.
