This is really bad abuse of terminology. Non-copyleft and copyleft licenses are all both open source and free software licenses. They're all free and open, which are synonyms in the context of software licensing. I think you'll confuse people if you use the terminology as you are using it (plus it's just plain wrong).

Personally, if I'm writing a hobby project then I want it to be copyleft. Of course I want it to be copyleft. Why wouldn't I? I don't want some company taking my work, making proprietary changes and improvements to it and then not releasing those back to me. Copyleft is simple courtesy that you'd expect anyway, codified into a license.
