First example that came to mind was actually Mac users who struggle with external monitors/projectors and things like screen sharing too. I agree they’re things that are so basic they should just work. Reality is often different even on other OSes.
Of course if you have a Windows home and everything works and then you try Linux and it struggles with a piece of equipment, it’s easy to blame Linux. You wouldn’t even be wrong. But you are oblivious to someone else’s experience who uses Linux exclusively and everything works for them, how many of those things wouldn’t work or work well with Windows.
Personally I’m a developer, so I care a lot about integrating parts of my development stack. A lot of those things don’t “just work” on Windows, or even Mac, so I’m happy to stick with Linux instead.
