You're absolutely correct on your assessment and it makes them sound absolutely ridiculous when you are on the other side of the fence. I have used Linux for decades and barely notice its issues. Every time I use Windows, all I notice are the issues. It has nothing to do with being biased towards one operating system or another. Rather, it is the outcome of being accustomed to something and unfamiliar with the other.
People should really try putting themselves into the place of those they are speaking to before making broad statements, and temper those statements with the realization that different people have different experiences and expectations.
