So long as you are consistent when it happens in reverse, I respect your objections.Yes, it’s wrong if the person of the other race adapting the story is profiting from the stories and those who are of the race in which the stories belong to are not. That’s what Joel Chandler Harris did.
Nowhere near the same with Princess and the Frog.
I will go ahead and make it clear, however, that I could not care less if Japan made a film adaptation of Snow White and not a single European saw a dime for it, so I'm not particularly offended by what Joel Chandler Harris did, unless there's more to your point that I'm not fully seeing, which I admit is possible. I just don't think it's a problem for cultures to be influenced by other cultures, but I know not everybody agrees with that.
