This is possibly an interesting extension [1]. I just generally don't follow recommendations. But my kids love it, and they use my account (Premium, else they get all kind of inappropriate ads (which is even illegal)), so I have to be careful. So the other day I wanted to look into what the other political side had to say about something. You know, as a matter of broadening my view to gain some understanding. Boy, did I regret, as I was getting sucked into some kind of conspiracy bubble. My wife asked me what on earth I watched. So I ended up trying to have YouTube profile me as little as possible (via settings). Didn't fully solve it, but it is much more clean now. And if I do watch something which I don't want to be remembered: private browsing mode. I do this for porn, but unfortunately they do profile my IP address (so I should use a VPN).
