Why? Because it's the best for my needs. It also honors the "BSD tradition" and has fantastic backward compatibility.

I have been running NetBSD since before linux existed. Why switch to something less familiar, and, honestly, less friendly?

NetBSD is the emacs of OSs - always there, reliable, maintainable, fast, clean.

With a fantastic, friendly user community. Give it a go https://NetBSD.Org/
