I don't believe they have seen Harmy's version /any/ pre-SE version. Also, Adywan said in his recent interview that only ONE shot of the TIEs was CGI (for like a second and a half) and the rest are actual models and such. They complain about his adding CGI TIEs so that shows how much they know what they're talking about.

But yeah, they don't seem to understand the reasoning behind fan edits in general and are too immature to care to understand. They would rather have fun circle-jerking each other about how dumb they think people are.
