> Android (the OS part, the one you want opensourced) is pretty much not making any revenue (which is easy to see on the earnings report).

All licensed Android phones are also forced to bundle Google apps like Youtube, Chrome, Play Store, Google search, Drive etc. And all these products make Google a LOT of money. Not to mention the amount of personal data it helps Google collect. Google didn't buy and develop Android out of kindness for its customers.
