Despite the conjecture here, he still sounds awful. Especially if you’re rich and successful and you don’t even help friends who helped you.

Like if I was broke and working hard on some story and my friends helped me in some capacity, and it was always known it wouldn’t be for financial compensation but then it goes off and becomes a success I would definitely help them back. Maybe not like give them a credit on the book but a thank you shout out and maybe something off the record or something… Not ruin my relationships and be an ass
