Not surprised at all. Certainly one thing I would recommend if you believe you may fall foul of the government is switch to Linux, it probably won't stop them if they are determined enough but it could slow them down. The way proprietary operating systems work is essentially Apple or Microsoft always are a back door super user into your system where as on Linux if so inclined you can see everything that runs on your system as its all open source and in theory any super user actions need your password and permission. My guess is the tools they have available are less sophisticated for Linux systems just because its such a small percentage of desktop users.

Of course there is relatively little you can do about your smartphone because ultimately whatever OS it runs the phone itself runs on the baseband and Apple and Google are full of back doors on top of that.

If you want to do something in secret for god sake don't take your phone and don't say anything around it you wouldn't want the FBI to know unless the battery is out - then think how many phones can you take the battery out of these days...
