What I'm saying is that what people perceive to be "Android" is not the AOSP components, but the Google Apps components. You give an average user an AOSP only device and ask them to use it, their immediate complaint will be "How do I has Facebook".
That's how the GApps == Android works. To an average end user, given an AOSP device, will find it totally useless.
Nokia/Kindle Fire/etc devices which implement their own Market aren't bare AOSP devices as they do have some sort of market. They're still not really Android how most would perceive them, but they add enough functionality to be able to install Facebook for an average user.
Regardless, I've had this argument a kazillion times in IRC about how AOSP !== Android, and I'm not really prepared to repeat myself again for the kazillionth time.
