> uBlock Origin has been able to block 100% of Youtube ads in my experience so far;

What about mobile and the YouTube app?

I don't use the Youtube app on mobile, precisely because I've been unable to block ads in it. Instead, I do one of two things: either pre-download the video with yt-dlp then copy the .mp4 to my phone and watch it with the VLC app, or else if there's a video I need to watch right now and all I have is my phone, I use the NewPipe app (https://github.com/TeamNewPipe/NewPipe, GPL 3, has to be sideloaded because of course Google won't allow it in the Google Play store) to watch the video without ads. Every so often Google changes the internals of how Youtube works, and then NewPipe fails until they get out a new release, but it's been working fine for the past several months.

		Android Firefox has ublock origin support. And there is also https://revanced.app/ Though I personally just pay the premium sub, as I use it to play music on most days.

		I'm not familiar with NewPipe, I'll take a look! Unfortunately yt-dlp is a no-go for me, I don't plan so far ahead and I mostly watch YouTube from my phone, usually when cooking dinner, doing the dishes, etc. That's why simply paying for YouTube Premium is (for me, and for now) the path of least friction. Paying off the thugs so they leave me alone :(
