To be clear, I wasn't intending to come across as attacking voz, only pointing out that I don't think anyone "in the know" at Meta/Facebook would admit to it even if they were doing it, so hearing "This is nonsense." doesn't really tell anybody much. They would likely say the same thing whether they thought it was nonsense or not.

No, they would likely not say anything. Explicitly denying it is saying something. But also - just to backup your claim how do you fingerprint a model? It seems logically impossible to me, if you are trying to mimic a certain intelligence, and you specifically "unmimic" it... then you may as well not try.
