Here's the real as I see it.
Dame knows he only has one card left to play and that's a no holds barred tell all book revealing shit about Jay and others which is the only way it's going to sell.
But for someone he always talks about gossiping and chatty patty shit it's going to be hard to justify this.
His solution is to convince everyone that he's been betrayed, blackballed, left for dead, etc. by the same people he's made famous and made millions for which has gotten so out of hand that his only recourse is to publicly air these grievances out in order to protect himself, his family and his name.
