Lets get real. A $20m tax write off to charity has nothing to do with AdSense or AdWords swag gifts. If you were expecting a gift from Google - you got stiffed. Your "gift" did not go to charity. If it did go to charity in your name, then ask Google for documentation to that effect so that you can take it off your taxes. To even mention the two in the same breath is a disservice to the charities and to AdSense operators. Google gives money every year to charity - so do alot of businesses. $20 million isn't even good pocket changes to google. These two events are totally unrelated. Nothing but political pr slight-of-hand at work.
