This is what i did when i got the "we are going to start blocking playback ...." Message and it worked great. Moral of the story is track content creators you like with rss and you dont need to be logged in.
I just have to figure out how to implement sponsor-block, to remove the "this video is sponsored by shadow raid vpn" messages... probably can be done with ffmpeg :)
yt-dlp --sponsorblock-remove defaultnot that you shouldn't use yt-dlp, because it's great!
and yes, as others mention - you can have yt-dlp use sponsorblock to cut out the ad sections too.
