No one is doubting this dude went to a dinner party and heard what he heard. But it's still anecdotal and thirdhand evidence - there's no verification. It clearly still gets under adr's skin that people don't take his word as gospel or platform his own opinions about the last years of the show. But it's not up to him.
I do think it's possible P&G could someday let some of that stuff back out if they have it, since they're getting back into the soap business with The Gates. More obscure shows have turned up on Prime, Pluto or Tubi. But I'm not holding my breath.
