Why are people WEIRD about NEWJEANS' Impact?

I had to get this off my chest cos I've not noticed this with any other group I've reacted to. 

What's with the dismissal and denial? Where does that stem from? OBVIOUSLY this is multi-layered and the music soundscape is not purely based off of NEWJEANS' sound however you can't help but see the parts that they HAVE influenced. 

Hope they have a comeback in the future.
