Actually as a Google shareholder I want the Gmail team to share customer data with the YouTube team. I doubt that Google's privacy policy prevents this, and it would certainly offer better targeting of ads and therefore more revenue. Is it considered evil for one branch of a company to share customer data with another branch? Wouldn't most users expect you to do that?
