I'm going to go out on a limb and say you don't listen to much "modern pop" - the production quality of the biggest mainstream pop is _extremely_ high at this point, and while "worse voice" is obviously subjective, this really wouldn't be anything stand-out in that regard even if it didn't sound like a robot.

I mean, if you dislike the sound of an autotuned voice (which a lot of people do), then there are a lot of modern(ish?) pop artists that use it heavily who you're gonna hate: Travis Scott, Lizzo, Neo, Kesha, T-Pain, Doja Cat ...

I'd say that is more about hip-hop, really. (And a couple of names that aren't exactly the most relevant to this decade)
