I don't really think your Arkham comparison works. People who buy those statues enjoy playing the games and having statues based on the game. This Daredevil statue is based on nothing that people have read, watched, or played. It's just a made up costume by Sideshow. Sideshow basically thinks that their designs are better than the subject matter that made people fans in the first place.
That being said, I don't really have a problem with this statue. However, I can get why people who want a classic Daredevil for their collection would be upset.
I like my statues to be as realistic as possible. In my mind, superheroes like DD and Batman would be constantly improving their costume, so it doesn't bother me if a new comic artist, or statue sculptor, makes changes, as long as those changes look cool and make sense. I don't need to see that modified costume in a movie/video game/comic/TV show to somehow legitimize it.
