I agree. But to continue the point - even if I wanted to spend 40 gross hours of billable time at $200/hr for a single installation of a server OS, that doesn't necessarily mean that it's the right OS for the goal I'm trying to accomplish, no matter how bad or excellent the configuration experience happens to be. Conversations about the utility, costs, and feature sets of Windows vs. Linux. vs. macOS tend to ignore the reality that business conditions often dictate that you must use one or the other for a given use case. Sometimes you do have the option, and if you've already got an appreciable investment in one, then you tend to select for that one almost by default.
