Social networks seem to be unable to optimize for anything other than "engagement," which inevitably leads to amplifying compelling but technically incorrect and outright dangerous content.
The thing to remember is that YouTube is essentially designed to boost disinformation. As implemented they have no effective counterbalance to this.
Is it also "censorship" when the YT recommendation system effectively buries factual and useful information for some people just because it's less engaging than the misinformation they currently consume? Maybe so?
The solution seems pretty obvious to me. There's a middle ground between banning and allowing to run rampant - and that's to add human reviewers to counterbalance the terrible job currently being done by their automatic recommendation system, and manually down-rank disinformation so it is less likely to be surfaced automatically in peoples' playlists.
Google will never do it, because it would 1) require paying humans to do work, which is expensive, and 2) it wouldn't drive engagement and generate clicks.
So they just take the easy way out, so they can keep on doing what they do.
