The backlash surrounding the policy stems from how Google products can now interact and share information with one another. Under the terms of the old policy, a service like Google Docs couldn’t peer into a user’s Google Maps account. They were two separate products, even though a universal Google ID could be used to access either service. Now that the policies on each Google product have been condensed, different Google products can talk to each other. The company already had an alarmingly thorough knowledge of its users, and now all of that knowledge will be combined. Pundits have argued that this gives Google too much information.
On the other side of the spectrum, though, is the benefits that will stem from this new policy. One example given by the New York Daily News is that now if a user misspells the name of a friend in Google Docs, Docs can alert them to this by crosschecking that person’s Gmail history. Other benefits include being able to alert users to calendar appointments if, say, they have a calendar event scheduled in LA but Google’s Android GPS says the person is still in Indianapolis.
