The author seems to miss the point of filter bubbles. There's a known cognitive bias where people tend to seek out information that mainly validates their existing views. Filter bubbles become a major enabler of that, allowing them to develop horse blinders to reality. Filter bubbles can lead people down into more extremist views that don't mesh with reality, rather than giving them exposure to counterarguments and allowing them to develop a more well-rounded view.
