I'd say it was unbelievable but it's not. If MS gives intelligence agencies a free pass we're all stuffed. I am seriously considering going back to a Linux or BSD based OS full time.
Already ahead of you brother. My entire home infrastructure is primarily locked down BSD, Debian, Linux. ChromeOS. A few AndroidOS devices. The primary reason for this is security and privacy, they are all very very quiet little friends. Also since they are already quite heavily secured, it's trivial to add additional lockdowns and once you place them behind a UTM/NGFW they become virtually bulletproof. There are only 3 actively used Windows Systems in the home maintained for gamers, and the security theater is still being played on all of those.
However, I do have the Windows Systems segregated by physical zones away from the primary network or other devices. That should tell you exactly how much I trust Windows - which is ZERO. I won't even give those Windows boxes user-space access to the UTM Admin. The only thing they can talk to on the local network is my DNS server and that's limited to the DNS protocol only, to a specific IP, with IDS DPI scanning of DNS traffic to ensure no DNS malformation activity.
One of the most paranoid guys I work with (and no, I am not that person) has gone back to using a locked rolodex on his desk at home for password storage. He constantly mumbles things like 'it's all broken, it's all compromised, we have no hope' as he wanders these hallowed halls.
