Russian government asked tech department what the best replacement for Windows would be
All 3 suggestions are Linux (because what else could it be, since there is nothing else?). Astra Linux, Alt OS, and Red OS.
Russia didn't seem to even want to switch from Windows, but Microsoft has pulled out of Russia and stopped shipping to there, and stopped security updates and blocking access to Windows installation files.
China has its own linux, called Kailin Linux.
