Political leadership isn't technically knowledgeable. It is focused on building large social networks of agreeable people. And Linux is an application by and for techies, not CEOs or social clubs. Consequently, when you've got six old white Harvard Alums in a room discussing how to run the country, one of them is going to be a Microsoft C-level and none of them are going to mention an alternative OS (except maybe Apple, in so far as they want their phone to magically integrate with a hostile OS rival).
Switch to Linux already and have computers that you can trust
A lot of these Microsoft features are about internal surveillance of staff and accumulating behavior patterns for future automation of service. This is not intended to be about building trust in the OS from the perspective of system security. Its more about finding patterns in human behavior that can be leveraged to reduce the size and pay-scale of your work force.
To that end, Microsoft is a highly valued partner while the Linux developers are an outright threat.
