I'm originally from Canada. Barely any christian rock made it to radio. Probably because they didn't want to be on the same station as the evil rock bands. I didn't know it was a thing until university when my neighbour tried to get me to listen to Switchfoot after hearing me listening to Skinny Puppy or something like that.

That's fair. Basically since the 80s America has had a counterculture of Christians explicitly rejecting the secularity of society and attempting to create an alternative media landscape that will both pull secular people into the extreme Christian movement using counterculture aesthetics and concepts (ok that actually began in the 70s when they were preaching to burnt out hippies, lots of cults began with that), as well as to prevent their young people from leaving for these things.

"You don't need to go be a hippie, you can be a Jesus freak and talk about peace and love and hear how the hippie life of sex and drugs was bad." And copy and paste for rock, metal, and whatever else. So long as there was something there beyond what they consider immoral they'll do it, and it's extended to stuff like just tv.
