I would call it heavy dubstep(HD), there has been HD for years now obviously, it's just a different take on the base genre. Original, true dubstep branched off from garage in the late 90's, at the time it really did not even have a name from my understanding. It got darker, more bass directed, and moved away from the cheesy vocals and pop trends that had begun to kill garage. Skream has been a pioneer in the genre, he was one of the main people to add something extra, something more heavy to the music at the start. The main difference in my eyes between the song you posted and the shit filling mainstream american media is the lack of shitty vocals, a more simplified/consistant heavy sound(not bouncing around to something new every 2 seconds, which is the main thing with brostep now), and you can still hear the dub influence in the sound(while small, it is still there). All forms of music evolve, and dubstep is still very young in terms of musical age, so it will continue to change. But when you compare that skream track and a skrillex track to something like this(bellow), which is closer to the roots of the genre? The answer is pretty clear to me.
