I hope YouTube (and Google as a whole) are applying these changes to all content. If they are specifically altering the behavior for only certain content (e.g. flat earth videos), I think that raises some serious red flags. I don't want YouTube to be the arbiters of what people watch based on their compass, which is going to have an obvious bias. The reality is that almost all online platforms are driven by user behavior. If those user behaviors lead to relationships between videos that drive recommendations, then that should be respected. Who is YouTube to say that's bad? However, if the quality of recommendations is skewed by one group of heavy users (i.e. it is being gamed), they could consider tweaking how much weight is given to such users and apply it across the board. That is, they need to apply such changes not just to 'conspiracy theory' videos but also to things like political videos from the left (and the right), which surely experience the same skew in recommendations from a minority of users. An aside: some comments here seem to say that YouTube should keep this content but 'stop promoting it'. Well not recommending content is in effect the same as censoring it outright. If an order of magnitude fewer users find some content, the net impact is the same.
