With regards to your first question about the $31 billion in revenue and the $22 billion in profits: The marginal profits seem a bit excessive. For example, they could put some of those profits into improving the security model.
Let me see if I understand you new complaint. Google spent $9B in cost for Android. $9B which included security and you are complaining they should have spent more. How would you know? Google didn't break down the cost into how much it spent on each component.
Need I remind you that no one is forced to use Android. And that Android is open source.
No matter how large the profit, there is a bigger number available. You can't cure greed with any amount of cash or booze.
No you missed the whole point. Google is a business. It has to pay for its operating expenses somehow. You seem to think that being altruistic will keep their doors open and their people paid. It doesn't. Now the amount of money of profit is another thing completely separate of whether Google is evil or not.
