Columbia Law School professor and author Tim Wu Has raised serious allegations against Google, asserting that "Google is degrading its own search results by excluding its competitors at the expense of its users". Oxford University's Antitrust Enforcement Symposium was held last weekend, the paper, delivered over, is Particularly interesting in that Tim Wu was in fact a Google fellow and proponent of net neutrality. Wu also authored "The Master Switch: The Rise and Fall of Information Empires".
Tim Wu, together with Michael Luca from Harvard and the data science team form Yelp (an infamous alleged online extortion platform, albeit immune due to the ironically titled section § 230C of the Communications Decency Act), used A/B testing to demonstrate how Google's algorithmic bias to favor its own content cuts engagement. Consequently, Google is "reducing social welfare", according to the paper. In other words, Google is displaying deficient search results, in favor of its own reviews, to the detriment of Web rivals.
Tim Wu is also the author of The Master Switch, Network Neutrality, Broadband Discrimination and other works. In 2013 he was named one of America's 100 Most Influential Lawyers.
