This is correct of course but we can't ignore that Windows computer are ubiquitous nowadays. Alternatives like Tuxedo or System76 are either pricier or are missing options such as keyboard layouts, delivery to non US/CAN/AUS and European countries, world wide support (in your language). Also, people just know Windows. Those issues might go away in time but there's non-zero friction to acquiring Linux hardware imo.
