If I had to guess, its a bygones be bygones scenario. The story makes the brand look good, and to my knowledge isn’t costing them anything. So as long as he doesn’t target them for money they’ll probably just let it slide as it was free good publicity.

Wasn’t his character left out of the rest of the show do to him being told he wasn’t gonna live long? Payne just sorta dipped, even Arya forgot him. He was a good cast though.
