Not surprising, curated content will do more harm in the long run though.
For example, results from Google are curated with a combination of factors including your local region, when you can search for political issues/information for example you can get different results than others, based on what their system *thinks* you should be delivered based on your habits Google knows about you. That goes for everything, Google results and advertising are not universal for everyone and can vary from an individual's habits, to their local region habits, etc.
