I have the same impression after comparing it recently to Spotify. On Spotify there is no dislike button so I can't say, please don't play this song anymore, I can only ban the entire artist which is definitely not what I want and also not as easy to do. Then when it comes to generated playlist out of one song, the Spotify songs seem irrelevant to the song they start from, while the yt songs are at the very least in the same genre.
And the interface works fine, I'm never sure what people talk about when they say it's not good.
They already had it and it was working just fine. They tore it down and went full coal and some gas. Now wind and solar are taking over slowly, but it's been years with more pollution and more radiation than any already working nuclear plant would have emmited.
