I deleted my whole history last week, and within a day YouTube was recommending me anime openings for things I have not had any interest in for 10 years. I'm pretty sure it's at least partially bullshit.

I ended up just deleting my whole Google account. I'm making do with an RSS reader and yt-dlp for now, but I'm already so fed up with that whole process that I'm making a simple QT app that does the RSS reading and yt-dlp calling for me. Akregator fucking sucks, by the way. Every time I shut down my PC without closing Akregator first, it loses its shit and does not remember any read statuses.
