Yes, and that's one side of the relationship. The other side is that YouTube provides a free platform for anyone to upload and watch videos, and it even suggests videos it thinks you might like. Everyone here benefits. I fail to see anything as nefarious as the term "addiction peddlers" and hard drug metaphors would imply. The problems described in the text sound like they're mostly caused by mental illness and/or lack of personal restraint, both of which are and should be outside of the scope of YouTube to solve (unless we want to start accept third parties robbing individuals of agency "for their own good").
