本文 argues that Google’s dominance in search stems not just from being the default on many devices, but from its vast trove of user data. This data, gathered from billions of daily searches, allows Google to refine its algorithms and deliver superior results compared to competitors, even if they were to use the same source code. The author cites the US Department of Justice case and leaked documents as evidence of Google using user behavior, such as clicks and query refinements, to improve search accuracy. While acknowledging that Bing employs similar tactics, the article questions whether Google's advantage, fueled by its 90% market share, is unfair to the point of illegality.
