A possible reason PvsG decided to focus on the wamp-rat aspect of Adywan's edit is because it does show a joining of the minds. For the most part one side of the argument has expressed their disapproval of the Special Editions changes, yet this sequence is one of those from the SE which ended up in the fan collaborated Adywan edit. So PvsG could be using it to show that there is some give and take from Lucasfilm and the Fan Editing Community towards the final definitive 'Star Wars'. Yeah that's probably a stretch...

On the 'any press is good press' side of this issue. Although there might be inaccuracies or tweaked opinions in the final doc, the upside of getting word out about the goals of this website and the goals of the fan editing community could outweight the initial misconceptions. If this thing does get a theatrical release, how many more people will end up aware of the work being accomplished here. And if their interest is great enough, they'll find the reasons for the tweaked opinions in the words in these forums.

Also for the first time, in the io9 interview they've talked about releasing the full interviews with some of the participants. That's a great resource, let's hope we hear more of this.
