Also, as I understand it, as long as it is a restoration it is also slightly more distanced from just a copy. As long as no money ever changes hands and people on the original sources I can see no action being taken.
If they wanted to sue Harmy, they could do it. But as he does not make any money from his releases and requests users to buy the official releases, they can’t claim he’s stealing their money. So if they decided to sue him, they would just make the fans angry, which is a horrible business decision, and as we see Lucasfilm under Disney’s ownership tries to please the fans of the original trilogy as much as possible.
TL:DR - these releases are definitely copyright infringement (at least according to US laws), but they have no reason to interfere. Don’t give them the reason please 😃
