Want a non-conspiracy example? Search "obama is gone" on youtube then on DuckDuckGo. Even a stupid crab rave meme is buried, presumably for the purposes of preventing Obama related conspiracy theories from emerging.

I'd still never park my kid on Youtube but things aren't like they were pre-adpocalypse.
One evening of video surfing and you'll practically trip over them. I have no idea how it is one could never notice this stuff. I clear cookies and have no account.
The difference I see is that I have an account with subscriptions and years of activity data. I guess the algorithm knows I don't click on that stuff so they stopped trying to show it to me. I'm very surprised to learn they are giving users these recommendations by default.
