Problem he is not addressing is that using an android maker to make android-like phones and trick people into a fragmented market is a problem. Furthermore, those without the true android os, will be disappointed citing how android sucks. They need to protect their image. It's either full android or go home.

You have to balance "don't be evil" with "this product needs xyz to survive or the competitor (apple) will murder us in the market."

Hence google's new strategy to patent everything and their mothers to protect themselves.
