An OS must have:
* Stable API/ABIs including for the kernel
* Wide software compatibility
* Decent QA/QC
* Can be used with any hardware it's meant to support
Linux on desktop has none of that.E.g. the open source AMD driver, amdgpu, has a gazillion of regressions and issues for any kernel: https://gitlab.freedesktop.org/drm/amd/-/issues
If it works for you, that's called "anecdotal evidence". That doesn't mean suddenly Linux has become an OS.
