It has a lot to do with the point at hand because you can't really attack Microsoft on their web tracking because they don't do any.

So if Google wanted to attack MS on the subject of privacy they'd have to go all the way to Skype to get some traction. So instead they attack on a front where Google is strong and Microsoft slightly weaker.

Google is anything but altruistic, their each and every move is to improve the bottom line for Google and their shareholders. If something is really altruistic it likely falls in their PR budget.

Scoping browser exploits in competitors products is not 'core business' for Google. Privacy violation is.
