It is most likely because their previous album "Digital Renegade" was a concept album about the rise of hackivist organizations like Anonymous.
Considering dubstep is part of the EDM category, and screamo is considered "scene" yeah that would be correct. Making it look like you are trying a bit too hard here. And this is literally
the only lines he has ever sung on any of their albums.
Anyways, I never was really into this band but New Demons is pretty beast. I read an interview not long ago where they talked about how personal this song was to them. I think this video conveys that pretty well.
