I paid for YT Premium for years until I noticed just how atrociously YT runs in Firefox. There were also the accusations that YT slows down the video pages for anybody with an adblocker... even if they're paying for Premium.
I block ads at the DNS level and am not about to tweak things forever just to de-mangle my paid-for YT experience. So I dropped Premium, started supporting channels that I actually watch directly via things like Patreon, and watch YT videos via tools like Invidious and yt-dlp.
Local video players such as mpv and IINA are so much better than the YT player has ever been in any browser and I don't have to worry about buffering. The bonus is that I can keep a backup of favorite videos sans baked-in ads or whatever customer-hostile tactic Google dreams up next.
Edit: for the information of anyone not yet realizing the following: the chances that some of us will let anyone keep track of our cultural activities is much, much less than zero, and surely less than our disposition to extermination. It is called, "The Basics". I know they are missed by many, but they ought to be informed.
