For OOT reconstructions/upscales like Harmy or DarkJedi, it depends on what their plans are. If they are going to re-release the OOT then maybe they're waiting to see if that stops all these fan edits, and if their release isn't completely insulting like the GOUT, then it really should. If they have no plans to release the OOT then I think they would've shut it down by now. Given how little Lucas seemed to care about fan edits I think Disney will want to go about dealing with them as peacefully as possible, and releasing the OOT would get rid of the need for projects like the Despecialized Edition. As for things like Adywan, I don't think they care since most people who would watch those probably already love and have/would purchase the films anyway (I say "would" because they may be waiting for the OOT). I agree that they may not be so quiet about it when it comes to Ep. VII, but again, if they do a good job then there won't be a need for such big fan edits like there were for the prequels. As for prequel fan edits, I don't think they care at all since no one wants to buy the real movies anyway.
