I use pomade and it surprised me how often its branded like that. I have seen at least three brands that unironically use flaming skeletons. Also I have to say dapper dan is not great (at least the modern kind).
Edit: Apparently the modern kind is the only kind. O Brother just made it up, and someone took the design and made it real in 2011.
I think its ok to enjoy art from terrible people as long as it isn't actually about their problematic aspects, and you are avoiding directly supporting that person by giving them money or drawing a lot of attention to them. Plus in this case there were a lot more minds involved than just Cosby's.
