"The larger issue to me is that Facebook is adding Instagram data to its own," says Ryan Calo, a privacy researcher at Stanford University's Center for Internet and Society. "Instagram users thought they were signing up for a simple service, of relatively little utility to advertisers or government. Now that data is likely to be combined with an entire social graph. I picture the consumer happily paddling down a data rivulet only to find themselves suddenly on the open waters of the social sea."

"Of course, for new data posted to Instagram, Facebook can set new terms."
Concerns about privacy have cropped up before during corporate acquisitions. Advocacy groups raised concerns -- in retrospect, alarmist ones -- about the possibility of targeted advertising post-Time Warner-AOL. Google's purchase of DoubleClick was another.
In a 2007 decision that's binding in California, the U.S. Court of Appeals for the Ninth Circuit has ruled that users need to be notified before a terms of service modification applies to them (in other words, a silent change isn't good enough). And a California federal district court took the same approach in a 2010 decision involving an E-Trade account maintenance fee.
