Here's all I'll say on this subject:
I dislike some of the 1997 changes, and most of the additional 2004 changes. But I don't think Lucas was wrong to make said changes - it's his film, therefore it's his prerogative. I only take issue with the use of the SE's as a replacement for the originals.
I also dislike some of the things Adywan has done (in ANH:R, at least). But I like a lot of what he's done, as well. And I don't have an issue with the fact that he's "pulling a Lucas" in changing the originals ... because he's not making these as a replacement for the originals. They're meant as an alternate version, a companion piece if you will, like the SE's should have been.
Not only that, but Ady has also worked on some fantastic projects that do more to preserve the originals than Lucas has ever done - his '97 Empire AVCHD, his '80 theatrical Empire DVD, his '99 theatrical TPM DVD, his announcement that he'll be doing a '77 SW restoration as well, and so on.
So I don't think it's fair to compare Adywan's work to what George did with the SE's - they're two entirely different beasts.
