On May 20 we wrote an article in which we echoed a new nothing surprising: South Korea plans to ditch Windows to use your own version of Linux. It is not surprising if we watch the news, but if we take into account that they would not do it for privacy or to annoy the United States, but for an economic issue. Those who are going to follow in the footsteps of the Asian country by leaving the Microsoft system are two countries close to them: Russia and China. The main difference is that these will do it for security.
North Korea has yet to decide whether to abandon Windows. It will do so if you get all your software to run on Linux without incompatibilities, something they will surely do. Then we have Russia and China: both will stop using Windows for a national security issue and will do so on their military equipment. The operating system that the Russians will use will be called AstraLinux, a derivative of Debian developed by the Russian company RusBITech since 2008.
Astra Linux, the operating system for Russian military equipment
Russia thinks Windows could contain back doors, something that they cannot verify because it is a closed operating system. Ultimately, the Russians believe that if they use Microsoft's operating system, the US intelligence services can spy on them without their realizing it.
As for the Chinese, the decision would have been made due to the technological war that began with the "Huawei Case". The difference with the Russians is that China will not use a Linux-based operating system, but one developed from scratch by themselves. Among the reasons are the leaks of Edward Snowden, who uncovered that both Linux, macOS and Windows are easily hackable by the United States. And, although there are Linux distributions from practically any country, the "father" of its kernel is half American.
Other reasons why China does not want to know anything about the US is that they want to block the mining of Bitcoins, they do not want to give the Americans any advantage in the war of AI (artificial intelligence) and that the CEO of Google denies plans for the Chinese search engine.
The only thing I can say about all this is that I am 100% agree to abandon Windows. I did it more than a decade ago and I am delighted, and that I did not do it for security reasons. Also, Chinese and Russians will have better health if they use less heavy systems than Microsoft's, right?
