I'm not OP but I pay because I want to support content creators. It also removes ads from players that don't have blocking, such as Roku.
Of course there are other ways to support creators such as donating and buying swag. I do that too.
By paying for youtube, you're supporting Google and walled gardens more than creators, I'd argue.
