Corey should name names if he is serious about changing things out there in LaLaLand.
He might not be naming the people because if he did, he’d open himself to a libel suit, even if the events happened. It would be pretty difficult to prove they happened, so many years after the fact, especially if Haim was his only corroborating witness. I’d imagine that Hollywood “moguls” would be able to outgun Feldman in the legal department pretty easily.
