The problem is that a very large percentage of people apparently don't really want "relevant, clear, researched, reliable, unbiased", they want to be told that they're the good guys, that all their problems are someone else's fault, and that they don't have to make any changes in their lives. And social media giving these people what they want creates a vicious circle that does real damage to society as a whole. A platitude like "free exchange of ideas" does not address this problem.
