The article for me reads that the recommendation system carries the Bias of Youtube. So it is a recommender system that allows control from the owner. This means this recommendation system is not free but it may "train" the consumer on a specific content and act as an echo chamber. Is earth flat? Of course not but should we punish people for thinking this? Our society says verbally no but its choices say otherwise, they try to do it through undemocratic processes (aka Youtube???). If we provide better education to these people or even a better Health System accessible to everyone we can have better results. IMHO in the long run Youtube will just send these people to other more "hospitable" platforms and I have a feeling that it will help increase the number of flat earthers. So Youtube is in an interaction with its customers not only to maintain their echo chamber but possibly engineer the echoes. The decrease in variability of members is a way. Do we need armadillos when we eat chicken?
