You can call it a ring-0 application if wish to argue about semantics or the definition of an OS but you really do end up sounding like an asshole. Every OS projects starts out as a "ring 0 application" running on bare metal. An application which does nothing except handle interrupts and spew out numbers on the screen to tell that it is working. And most OS projects never really evolve a lot past that, because they are primarily intended as educational tools for the author and nothing else. If you had a point, you could have made it in a way that makes you seem like a decent person, not an angry antisocial geek.
