None of that matters to companies who want to hire an offshore tech to click things in the MMC and maybe write a Powershell script to solve something really quick. Especially small companies who can't afford an entire IT department.
All of the Linux management tools are good, but they do not integrate as tightly with the OS and there are several competing ones. Microsoft has one tool and one thing to learn and that's it.
I say this as someone who has managed a fleet of Linux systems and whose current work is 100% Linux based. If a company can throw a smaller amount of money at something then they'll do it
Windows: I can pay a low skilled admin who knows how to run prebuilt tools
Linux: I require a higher skilled admin who knows how to architect and build things
Because Linux has been built by developers for developers, it eschews braindead administration as a feature, because that's not something its dev community ever required.
That's changed somewhat in the past 15 years, but still lags Windows substantially.
