A man named Raghavan has been taken on as a major operational manager for yahoo, ibm, etc. Seems his direction of their operations lines up with a sudden collapse in quality in the areas he was at. Regardless everyone seems to discuss how he is one of the best researchers in field. The dark design, and other issues, google has been seeing an increase in, for years, is basically his direction and, while he isn't the CEO, he basically runs google.
