It's been very hard to explain to my organisation that Windows Server is dead. We haven't deployed a system to it in two years, everything is some kind of dockerised linux thing but the "we're a Microsoft shop" idea prevails.
In the end we decided to just let the management think what they want. I've been more of a Unix person for 40 years but I kind of miss the "good" versions of Microsoft Server - in the 1990s / early 2000s it was a real contender. If they hadn't doubled down on weird things like Powershell it might still be a contender.
