I don’t see the publicity as a problem at all. Either lucasfilm continues not to care, they see it’s cutting into their profits and decide to do their own OOT release, or they C&D anyways and piss off the fans. Given that since the sale to Disney, they seem to be focusing the whole company around fan relations, I doubt they’d do something that so publicly foresakes them.

Now I’ve heard from what I consider to be a pretty reliable source from Disney (not lucasfilm so take it with a grain of salt but still) that an OOT release is part of the plan to be released within the next couple years, probably alongside another release. So my guess is that they’re going to turn a blind eye to this stuff in the meantime, especially since the publicity helps fuel demand for an official release, then when they release their oot, they’ll probably start cracking down on fan releases a bit more.
