All these 'telemetry tales' are just hogwash. Forrest Gump wouldn't have needed any telemetry to predict in early 2012 that murdering the Start Menu by decree and force-feeding Metro down the throats would make The Tiles Wonder capsize and founder. A then competent Microsoft team didn't need any telemetry in 1995 to create an efficient GUI, a 20-person field study was enough. As Formfiller says, what a crazy f***ed up industry this is.
