But they have spoken out. Bob Iger (Disney CEO) has said, “I’ve felt, for as long as I’ve been CEO, that Song of the South – even with a disclaimer – was just not appropriate in today’s world. Given the depictions in some of those films, to bring them out today without some form or another, without offending people. So we’ve decided not to do that.”
And since Splash Mountain is directly based upon Song of the South and uses the principal cartoon characters from the film and uses direct quotes from Uncle Remus, it is obvious that the attraction too is not appropriate in today's world as well.
Frankly, I don't think TWDC wants to admit they were unwitting dupes in endorsing white supremacy.
