We live in a post-#ReleaseTheSnyderCut world now, where something that no reasonable person thought would ever happen is now being financed to the tune of $70 million. The studios are all looking for ways to make money on the cheap with their business disrupted due to the current unpleasantness, and an OOT restoration would cost a small fraction of what AT&T is spending to finish the Snyder Cut.
My final input is Disney may be evil, heartless and fake-woke, but they aren’t stupid. They saw value in buying Marvel, Star Wars, and 20th Century Fox with huge aspirations in mind and these now look like genius moves. They’ve also lobbied to Congress to prevent Mickey Mouse from hitting the public domain. They didn’t gain their corporate power and influence by dumb luck.
When/if Star Wars hits the public domain many years from now, as far as I know, it means anyone can put Darth Vader into their movies or merchandise. The studio will keep the negatives, sources, and distribution rights, but it’s possible creating fan projects would no longer be piracy.
In short, they’ll release the theatrical cuts when they deem it best for business.
