Nobody in their right minds would read Youtube comments. It's like Facebook comments or Twitch's chat, if you have the possibility to ignore their existence it's good. And thinking they represent everyone is... not really true (in absence of a good non insulting word). It's just a loud minority, like everywhere. People who don't like something often shout their opinion louder than those who like it, because thos who like it just don't see any problems and are like '' 'kay it's cool" and they move on. Only those who feel like the world is crumbling and coming to an end because of that UI keeps on commenting on youtube ^^
I would say the most representative element of the silent majority is the like/dislike ratio. And I'm sorry to inform you that you are currently "losing" on that side
