I wholeheartedly disagree. Google is also in the business of using any tracking data it can gather on users to deliver ads. Google's primary money maker is advertising, whether in search results or in banner ads. Their customers are not their email/chat/docs users, their customers are the companies that buy advertising. Email/chat/docs users are the product that they sell to advertisers when they promise that the ads will reach an audience. The free services they offer are the honey pot to convince the users to get an account and be tracked. Google is in the same precarious position as Facebook, people just talk about it less.
