Sure, I get that. But that makes it a very opinionated form of free and open. While permissive licenses like Apache and MIT do have terms, they are much more akin to saying "here is a thing I made, and I'm sharing it with whoever wants to use it and whatever they want to do with it". Whereas copyleft licenses are more like "I'll share this with you, but you have to use it in accordance with my beliefs".
While I accept that the OSI definition of "open source" is pretty much universally accepted and probably isn't going to change, I personally don't really feel like copyleft should qualify because of that level of control it exerts.
