> In the course of the spring, YouTube drafted a new policy that would ban videos trafficking in historical “denialism” (of the Holocaust, 9/11, Sandy Hook) and “supremacist” views (lauding the “white race,” arguing that men were intellectually superior to women).

Cool. So YouTube will force that group of people off their platform and magnify the intensity of their echo chamber in the process.

To many of those "problematic" videos other people have created detailed responses explaining why they are misguided. Now the other group won't see those rebuttals because they're on a different platform.

Thanks to what passes for a "good" recommendation engine nowadays people are already mostly subjected to content they already agree with - instead of content that might challenge their views and make them a better person.

This will continue until nobody's opinion is challenged ever (and doing so won't be socially acceptable in any case). I hope to never see the kind of society this leads too, but I fear we might be entering the endgame sooner rather than later.
