The general theme is the same as the article: less real estate dedicated to actual videos you might want to watch. There were two rows of completely useless garbage that I had to add to my uBlock Origin filter just now: one for Shorts (which I have blocked in the past) and a new one for some sort of Youtube Games thing (?) that looked like the worst AI generated slop you'd never want to play.
If this is the premium experience then I don't want it.
