It's... how recommendations work.
That is showing the user type of content they are interested in.
And there is absolutely nothing wrong with it.
After owning the same very active youtube account since 2007, youtube finally tried to radicalize me a few months back. I watched a single video from a more radical leftist (I guess class solidarity-ist) channel, and the very next loading of the homepage was at least half extreme leftist and extreme far right channels, trying to tell me that "democrats are trying to kill millions of babies a year" and "republicans are trying to instate a theocracy tomorrow" and "why you shouldn't believe anything (((they))) tell you". Google has known my political affiliation and opinions for over a decade, and still tried to show me OAN stuff, because hey I'm radicalizable right now and that's pretty profitable.
I've watched slightly leftist youtube videos for years now, and youtube never tried to radicalize me, but the second I dipped my toe into the dark and disgusting pool of extremism, that's all youtube wanted to show me. These videos were not meant to inform, but to enrage. The fact of the matter is that extremist content is just way better at activating much more extreme emotional responses, which fun story, leads to more engagement. So the algorithm LOVES pushing people towards extremeism, because it's super effective at doing what Daddy Google tells it to do, which is to get people more "engaged"
Overconsumption has health consequences.
YT is a drug pusher. In the worse of ways
I notice that the moment I watch a video slightly "off center" it goes full slippery slope on my recommendations. No kidding
"Ah but this is what it should do". No, it shouldn't
To not give a political example, this is like chasing and knocking on people's doors at dinner time with a full McD meal because you had a frozen yogurt in the afternoon
Well, but YT does exactly that with Autoplay (and the recommendations are based on the last video seen)
Even if the algo is fair to you, it could be devastating to the more feeble-minded.. And you would never know, until some clownish grifter caricature became leader of the free world, wink. Even then, how would you trace that critical little 2% vote shift back to a particular algorithm?
