It's some dude who is supposedly a professional translator and he's bashing on fansub groups because basically they're doing a better job than him. He picks terrible examples of mostly terrible groups and then takes them as the general stuff fansub-groups deliver. He also talks some bull about karaoke and why groups are bad who do flashy karaoke (I couldn't care less about karaoke, but really, who cares if it's there?) and how it's very unprofessional. Well he seems to forget that most of those guys do it for the fun of it and not because they want to be pro-amateurs.
