> a modest fee for a non-tracking, ad-free, non-enshittified YouTube
And YT Premium is
[x] modest fee - I could argue that either way (is $14/mo really "modest"?), but let's allow it
[ ] non-tracking - not that I'm aware of
[~] ad-free - partially; right now YT itself won't add more ads, so you're just left with the ads that uploaders embed
[~] non-enshittified - depends what you mean; ex. I believe it does restore the ability to play audio with the screen off, but not downvoting
