that’s not the experience of the majority of people in this thread
I'm willing to bet the majority of people in this thread already forgot about the "linuxism" they had to deal with when they were starting, and are experienced enough to handle any new ones as they come along.
Don’t you think there would be a tiny bit more Windows dominance on the servers side if the opposite were true?
Linux dominates the server realm for a completely different reason - Linux-based servers supported hot-updates much sooner than Windows Server did, and in systems where uptime was critical, people chose Linux. That also meant that the vast majority of "server admins" had Linux experience which also contributed.
This is slowly changing now - if you look at market stats, you can see that Windows Server is (painfully slowly, granted) regaining some momentum.
EDIT: also, fun fact - I used to work at a company that had around 300 MacBooks and 2500 Windows devices. Back then I was working as a Service Desk agent. The distribution of incidents for Windows and MacOS we were getting was VERY close to 50-50... So, it seems to me that "Windows is known, has been known, and probably will be known for having shit break randomly" mostly among people who don't use Windows.
