You can't really make your favorite content creators switch to other platforms, so the best thing you can do for now is use a privacy-preseving frontend for YT. I can highly recommend Piped for PC and LibreTube for Android. They allow you to watch all YT videos and manage your subs/playlists without having a YT account or using the YT site or app. You can even self-host a Piped server if you want to.
Edit: So the major difference between Piped+LibreTube and NewPipe is that Piped is a website that handles the YT scraping and sub/playlist management for you, and the LibreTube app just connects to it like the YT app connects to the YT website. This means you can access it from your browser, synchronize your subs/playlists between devices and also hide your IP from Google servers. NewPipe accesses YT directly from your phone, so it has to do all that by itself and on every device separately.
Basically:
- YouTube app or browser => YouTube website (has user data)
- NewPipe app (has user data) => YouTube website
- LibreTube app or browser => Piped website (has user data) => YouTube website
