Well. I do get your point and I am aware of the situation and how Google pivoted away from a truly open source OS by systematically moving components like the keyboard to separate closed source apps. The fact remains though that it's Android Open Source Project where all Android systems are based on. It's become sort of a GNU/Linux kind of distinction where the "certified" Android is AOSP + Google. Though the situation is not that clear because there are other Android based phones that do not contain the Google layer but are still Android.
