I am afraid that users cannot evade government surveillance. Sure users can encrypt their mail and other content but many relevant parts of user communication will remain public. The importance of metadata for surveillance cannot be overestimated. In addition, encryption and efficient communication bite each other – there is not just momentary inconvenience, there is constant inconvenience. Just an example: The OS X 10.8 version of GPGTools, essential if you want to use GPG not just on the command line, just became available a few weeks ago. Users who wanted to use the current version of OS X and GPGTools, had to revert to a beta version. In a productive IT environment, beta versions are not acceptable.
