I have been a DJ for about 25 years, playing in the US and Europe so I can at least talk about how the terms are used in those places. EDM used to mean something close to “electronic music”, but as of about 10 years ago or so it has come to mean a quite specific subgenre.
Hm fair enough, I am probably just out of touch then, which makes sense. I used to DJ back in the late 2000s, 2010s, so that's where my perspective comes from. I never played dubstep, but the commercial uprising of dubstep was about when I stopped playing along.
