No, you're absolutely right.Yeah, it would be difficult, but I think that burden should come with them deciding to use this source material.
They've done plenty of videos on the art style, why it was chosen and how they executed it. I think a video or two about the racist history of the art and how they made sure avoid stereotypes would have been a good way to respect that history and educate.
Again, I'm not really criticizing them, just offering solutions going forward
