GL of course can say whatever he wants on this matter. He's the creator of SW after all. All respect due.
My view on the fan edit- thing is pretty straight forward. GL is bitter because he doesn't get WHY fans take issue with his edits vs Ady's. Ady is respecting the original films arguably more than GL has. He's also going through the movies with a fine tooth comb and fixing/enhancing all sorts or small/large things. This is a can of worms GL opened btw.
In short, AdY is crafting superior SE's. And he's doing it mostly himself with the help of other talented fans. A true labor of love that puts the 97, 2004 and blu SE's to shame.
Despite GL and ILM giving the movies "3 quality control passes" we still have crappy inconsistent sabers and other nagging problems. If GL had created awesome SE's from the start there would be no need for Adywan's edits.
The backlash GL got was because he kept the theatrcial versions from fans so that left that hardcore fan-base out in the cold. And those of us who are cool with the SE's got lackluster inconsistent versions of the SE movies. That's two large portions of the fan-base left dissatisfied.
