My setup is somewhat unique. I run Linux and love the command line/terminal emulator. I use newsboat rss reader which reads a text file that has a bunch of YouTube links listed one per line.

These urls were sourced directly from the youtube channels I want to subscribe to. In your browser, Ctrl+u opens up the html. Ctrl+f opens find, search “rss”. Adjacent to the first search result is the rss url to be put into the aforementioned file.

In newsboat, i can browse the latest updates to that channel. Hitting “o” opens my browser with the latest video. To boot, I use a redirection extension that takes that url and redirects to an invidious instance. Noscript extension prevents any javascript and I just copy the url {ctrl+L and then ctrl±c)

Finally I use yt-dlp in the terminal, pasting the url as its last argument (ctrl+shift+v in most terminal emulators). An alias wrapper immediately adds flags for medium quality (highest is often massive file size), subtitles, and sponsorblock (cuts out mentions of sponsirs via sponsorblock api). I also have similar aliases for high quality vids if I want them and also just extract audio for music. I watch/listen using mpv.

This is how I generally watch YT vids on my desktop. On mobile I use GrapheneOS and Libretube. Google has to send a CSV of your subs if you request it. Grabbed that a while back, uploaded it to Libretube, and haven’t gone directly to youtube cept to grab rss urls since. Btw, you can grab rss from invidious in a similar fashion, but I grab rss directly from youtube in case that invidious instance goes down.
