Well Disney is the embodiment of evil.
Think about it tho. What reason would Disney really have to dick around with a film who’s production they had no involvement with? And to add something as meaningless and trivial as Greedo saying Macklunkey? That is something that could have only happened under Lucas. There isn’t one instance I can think of where a film studio has ever randomly inserted new material into someone else’s film for no real reason like that.
Disney couldn’t care less about the original 6 films. They bought Lucasfilm so they could produce new material and exploit the franchise’s marketing potential to the maximum. Can you imagine someone at Disney going “You know what? We really should add a new shot into the original Star Wars film where Greedo says Macklunkey!”?
Same deal with Fox. Lucas still had total control over Lucasfilm by that point. There is no way he would let someone else add random crap to his films without his consent. Every inane change you have ever seen in a Star Wars film was done under the supervision of George Lucas. That is the whole reason the original unaltered versions aren’t available, because George Lucas doesn’t want them to be.
