It's worth noting that at the same time that the FBI is asking for this surveillance power, legislation has been introduced in Congress to update ECPA and require warrants for access to all email (that protection expires after 6 months under the current outdated law). We'll see how this shakes out, but the cloud providers like Google actually want better legal protection of the data stored on their servers so people have more confidence in giving them that data. In Google's view, Google's ability to spy on everything you do is better than the government's ability to spy on everything you do.
