Oh come on. Linux doesn't need more elitism, it needs more adoption.
Still, we should firmly resist any windowification attempt. My biggest concerns atm are rustrannies pushing to rewrite everything and the forced flatpack cancer, way more than newfriends.
Sadly I think a lot of software that makes linux more like windows will see the day in the wake of the massive adoption to come, and most of these small projects won't be bothered with packaging correctly which means it will all be snaps and flatpacks. And this is what worries me.
I don't think the UIs will be impacted much.
... except for the recent meme of not having an 'Apply' button, which already started contaminating Linux years ago. This is to blame on the soydevs who imported this shit from their mobile UI coding jobs to Linux.
