Google is more and more showing that they really don't want to contribute to AOSP.
So for me, Android should be split out of Google. Maybe the other Android manufacturers will start contributing to AOSP, and maybe Android will die. But let me be honest: if Google keeps going this way, I will move to an iPhone (and I've been using and developing for Android forever). We may as well try the split, and if it fails I'll end up with an iPhone anyway.
