Google also cares about its earning reports and stock price. "Using the internet" doesn't pay the bills. Google is far from a charity. Its a multinational corporation beholden to its stock holders.
Google made a strategic decision to piss on its mobile division to help its maps division. This may not have been the wisest move and considering how google stock prices have been falling lately, well, wise moves is something it needs to focus on.
I just hope google knows what its doing. Apple is ruthless against Android, yet google seems to be pretty easy going with iOS.
