Amazon totally forked Android and ripped out all of the google bits, all of the default UI and made it into their own OS.
It's Android in that it will run Android apps but that's it.
In all other ways, Amazon's Android is competing with Google's Android, which is one of the reasons Amazon don't describe it as an Android tablet unless they are talking to developers.
It's actually a really interesting strategy, although from an Open Source perspective it's always a shame when companies fork successful projects for their own goals.
