I thought the SEC filings both have a number and a risk of being wrong?
Re:parroting, while that seems to have been a pejorative, I wasn't actually copying from anywhere, just a smb executive sensitive to this sort of thing during m&a as standard business discussions, so it's interesting that it's being repeated enough to accuse people here of 'parrot'ing!
There is no hard number. It mentions that they are just an estimate and could be off. They are labeled as MAUs, so that gives a lot of leniency depending on how "active" they are. It doesn't define bots either.
The SEC filings thing has been repeated even by Musk himself. It doesn't really help him.
