It sounds like you're happy with YOUR Linux. Good for you. But, it's not for everybody, and it's lacking for many, like the IT department at Munich.
Whatever suits your needs, should be enough, and there is no need to attack other people's preferences. I don't love Windows, but it's the prevalent way of doing things with PCs. I use what works and makes work easier to get done. Windows does everything I need or want, and then some!
The very best trait of computing is that it is many things to many people. The notion that is can be done anyway on most any chuck of hardware scaled to any size is just plain mind-boggling. Software has always tickled my brain, and I am sure it does yours.
I have 32K processors communicating by cell modules to a couple of cloud servers. One is Linux, the other is Windows. I am using homemade protocols and popular IOT protocols, depending on the application and customer preference. The cold hard truth is, I love the whole pile of crap end-to-end.
I do, however, enjoy being the devil's advocate. There is a demon within me that cries to get out as often as possible. ;-D
