YouTube ReVanced gets you completely adfree, configurably de-shittified Youtube with sponsorblock on your phone. (And Youtube Music ReVanced is premium YT music, for free, of course also without ads.)
And Smarttube Next does the same thing on Android TVs, FireTV, and probably some others I haven't used.
Sorry, but you're plain wrong on your first issue. Getting all your packages from one source is one of the biggest upsides of Linux.
