When I left Spotify I remember it being difficult at first, I went around to various competitors who were all objectively worse. I've been using YT music for a few years now too and while it is not as good by a long shot, it's good enough and I feel more in control of my musical journey. You're right that they don't change much, it almost feels like a forgotten product, which probably doesn't bode well for its future with Google being Google.
