it doesn't matter if he categorizes his music. i know that he doesn't but it is irrelevant because his music is categorized as dubstep.
by no means do you have to look into something to like it, but if you have a genuine interest in something shouldn't that encourage you to learn more about it? if you like the aesthetics of a painting, wouldn't you then want to learn more about the artist, his/her peers, and the associations of his/her movement? you don't have to learn about anything that interests you, but why remain ignorant when you can have a better understanding and maybe better appreciate the same interest?
i dont wanna give the impression that i'm "on a bandwagon of hate." maybe a bandwagon of understanding instead? expanding on that; i was lucky enough to be in the right places at the right times and i got into the inside loop of dubstep when it was just beginning to emerge in the us (matty g, signed to dub police, was living across from my grandparents in santa cruz, ca when he released his for the smokers/bitter love ep /claim). until fairly recently, dubstep was largely defined as having a 140bpm tempo, formulaic 2-step drum patterns (hence the dub in dubstep), largely ambient, and driven primarily by subbass. most popular dubstep, or brostep as its come to be known, doesn't fit most or even any of these parameters - hell most of it is much much closer to house music (prog house and electro house) in terms of song structure than what dubstep is.
sure i'm overly analytically elitist douchebag for knowing & sharing all this, but honestly there was a time when dubstep was really cool, experimental music. while there's still a lot of that being produced, the scene has exploded so fast that a lot of people come into it and don't seem to know or care jack shit about it.
