I think there's a difference between silencing people, and having an algorithm that railroads people down a polarization hole.

My biggest problem with YouTube isn't what it does/doesn't allow on its platform, it's that it will happily feed you a psychotic worldview if it keeps you on the site. I've had several family members go full conspiracy nut-job after engaging heavily with YouTube content.

I don't know what the answer is. I think many people would rightly argue that removing misinformation from the recommendation engine is synonymous with banning it. FWIW I'd be happy if recommendation engines generally were banned for being a societal cancer, but I'm probably in the minority here.
