I'm sure most people feel the opposite way. I've been using Windows and Macs for 20 years and I don't ever see myself ever using Linux as a desktop OS.

Among the subculture that would be the type to visit Hacker News (or Slashdot back in the day), this attitude emerged around 25 years ago. In the late 90s, there was widespread enthusiasm for the Linux desktop. I remember those days fondly. It was glorious. Then macOS (or OS X as we called it) swept away a lot of people. A lot of them would get hostile or angry or mock people when they would mention they didn't join the Mac bandwagon.
