I'm not sure how smart it is to give people advice on privacy and which software to use to avoid surveillance via a traditional book. I'd much rather get my advice from EFF's Surveillance Self-Defense or TTC's Security In-a-Box because they're online and can be updated easily if a critical bug is discovered with any given popular privacy or security software. Capabilities change over time and when they do, you can't update a book as easy as you can update a website. If someone relies on this books' recommendations and think that they're secure when they're not for whatever reason, that's incredibly harmful. Reading the overview though, the book is also seems to be about history of obfuscation and protesting laws (?) so I guess it could be useful for people who're seeking that information, but I wouldn't recommend this or any book that acts like a tutorial to someone who's trying to learn more about online privacy.
