Alongside the issues of locking out specific genres out of VGM remixes (which, IMO, is just plain stupid), railing against dubstep is like railing against power metal or electro house. It's a genre, and there are different styles within the genre.
Dubstep in particular is a genre of electronic music, and genres of electronic music are categorized based on tempo and beat pattern. With this in mind, dubstep doesn't even need to be "bassy" to qualify as dubstep, the bassiness was just a style that got popular when Skrillex did (and no one bothered to actually consider what actually made him popular...namely his great melodic hooks alongside the bass). That kind of style been out of favor in mainstream EDM for a while now, most of the bandwagoners moving onto Moombahton or Trap.
Seriously though, I can't emphasize enough the differences in style that can exist between dubstep songs. These following tracks are all dubstep; note the beat pattern and tempo shared between them:
Gemini - 3D Romeo feat. Fabienne
Hadouken - The Comedown
Phetsta - Dance All Night
