It is an interesting philosophical point. On the one hand, I cannot disagree with
@TM2YC's point about just being freaking stoked that something I edited then saw an officially sanctioned release, it's like the pinnacle of fanediting success, and the edit was made without expressed consent, even though I truly believe when our rules are followed, fanedits are legally legitimate creations as long as faneditors do not seek profit off of them.
On the other-hand and using that same logic however, fanedits are intense labors to make happen, they are the result of a person (sometimes persons) creative vision and work, and it is questionable that a company can just take that and make profit without at minimum consulting, but possibly at least offering compensation of some kind (even if it's just an agreed upon credit).
I own Dune several times over, I would be tempted to buy this latest set if only to buy that 'official' spicediver version, which would mean that they are gaining profit for his work, without compensating him (not to dissimilar to the fact that studios benefit from fanedits in I often have bought movies I'd never have purchased because I want to see an edit, such as
@Wraith 's Split Broken Glass where I'd only ever have owned Unbreakable, but now I'll be ordering the other two films so I can watch his edit. In fact, M, Night has benefited a lot here, I'd never have owned several of his films were it not for fanedits... but that is another story).
I honestly don't know the the right answer or even if there can be one. I know that at the end of the day if the same thing happened to me, I'd just be happy it's getting out there. Anything beyond that would be gravy.
