War Readiness Means Removing Every Windows Installation and CALEA-Compliant Equipment
Russia, where Microsoft is seen as undesirable, has two neighbours on the northwestern edge: Norway and Finland (yes, Norway too shares a border with Russia).
In recent days there were NATO drills in the area, where large bombers practiced in case of another escalation. There are always warning signs and already some escalations in the Baltic Sea.
Finland is vulnerable for a whole bunch of reasons, not limited to so-called "hybrid" warfare, such as cable-cutting, GPS blocking, misinformation in Social Control Media, and weaponisation of immigrants. In Finland, and to some extent Norway as well, many people still use operating systems with back doors. This cannot possibly end well.
Imagine being SUPO (Finnish intelligence agency), seeing that so many people use Windows with deliberate back doors and on top of that there's the Communications Assistance for Law Enforcement Act (CALEA), which is a blessing to the Russian military.
Norway and Finland cannot afford any back doors in any of their systems. There are hostile forces looking to exploit these. When war breaks out it's already too late to start migrations (too chaotic to properly arrange replacements). █
