That may well be a big factor, and that's something that needs to be looked at more closely. Lots of people describe being drawn down the rabbithole by algorithmically driven suggestions which nudge them ever more extreme.
I have thought this for a while. Algorithms are something entirely new to human discourse.
Apparently I watched some alt-right-adjacent podcast or something, so for weeks youtube kept recommending seriously racist, fascist, white nationalist content. The algorithm was actively trying to lead me down the rabbit hole. Obviously it's learned that doing so increases engagement.
