It may be that they are guilty of what the movie exposes. Did you ever think of that??? Duh!
But again WORST POSSIBLE method of suppression. Disney owned the rights. All they had to do to make sure the movie never saw a screen was nothing. Don’t sell it, don’t release it, don’t anything it. If they were guilty of what the movie exposes THAT is how they would suppress it. How anybody with enough brains to tie a shoe would do it.
