You want proof that it's possible to watch #YouTube without being fed unwanted suggestions? I've always said that the YT suggestion engine is good to me. While I watch an enormous amount of YT relatively, I've never been offered any right wing garbage, for example.
And today I realized that even though I've heard the name "Mr. Beast" and vaguely recall hearing about his mass cataract surgery giveaway, I've never seen a Mr. Beast video, never been suggested one by YT, and knew effectively nothing about him until I read a CNN article today.
