I think what Disney may be worried about is the fact it is the entire money verse one part of the movie, such as the crows in Dumbo. And truefully, they are probably worrying for nothing. Also, it may all boil down to the use of the name Tar Baby, which is a put down towards African American. I think we will never know why they are not releasing it, just like unless you search you won't see the Donald Duck carton where he dreams he is German and following Hitler.
