I'm curious about this. I watch youtube a bunch and I never see rabbit hole videos. E.g. I've never seen the videos you mentioned. Is it because I'm signed in? I don't understand why I don't get any shady videos from youtube.
Sounds like a conspiracy theory.
On the other hand, I do see a lot of left-wing garbage, and YouTube leadership is known to lean in that direction.
Be glad. It depends on many factors what videos "the algorithm" thins you want to watch. Location, videos you already watched, probably gmail mail contents, purchase history from google pay, music you like... the list is endless and iam sure even for some google engineers not transparent at all. And don't you dare click on the wrong video by mistake! A simple dislike isnt gonna get you out of that hole.
Iam actually mostly fine because I barely watch youtube and ads and suggesstions are only one reason.
