If no one gives a shit then why change it? It's pretty clear people and companies do give a shit.
My personal opinion is that companies these days, Disney included, thrive on creating controversy as a means of advertising. Giving 0 fecks, in spite of their preaching, about creating a more cohesive society but trying to profiteer from discord instead.
I'm certainly all for more racial inclusion in Hollywood. I'm all for promoting more stories and more movies written, acted and voiced by people of diverse heritage. More Mulans, more Moanas etc. Simply replacing a character in a Hans Christian Andersen story with a black sketch and voice actor is pretty half-hearted and hamfisted attempt at creating diversity. And while I don't give a feck about what Disney do with their stories, I do care about its effects on the current political climate and discourse.
