My recollection is that this did not start life as a Disney property. If it does not, wouldn't it revert? If it does own it now, wouldn't it sell it?
Your post reads like an obituary, but I would think this will likely result in it becoming available to purchase/rent/stream elsewhere. Perhaps I am biased but having it on Disney+ (exclusively) is not my idea of available. Like Ann, I saw it when I was given access. I have always been a huge fan of his. Your comment about "hard media" is befuddling to me. Why would we care abut a deprecated technology?
