At this rate, there are probably only a few occasions to really be concerned about legal action, that being after The Force Awakens has had its theatrical run (so as not to hurt those ticket sales by upsetting fans who are already unsure about how Disney will treat Star Wars), or during/after an official release of the OOT (if they feel the DeEd could harm sales of a product they’re finally trying to sell). You’d think notoriety would be bad for something in this legal dark-grey area, but it’d be foolish to think this project is at all under the radar, surely people who could do something about it already know about it; they are either choosing not to do anything or biding their time. The damage is done (and they know it is their own fault), and Harmy might as well keep rolling out his improved versions until told otherwise. If anything, Harmy is proving there’s an audience for the OOT (and keeping the faith alive for us die hard OOT fans), which is valuable market research Disney is getting for free; it is not outside of reason for the DeEd to in some way help turn the tide in the right direction (and Disney could just be sitting back and seeing where things go).
