From the article:

"Since I started working with Snowden's documents, I have been using GPG, Silent Circle, Tails, OTR, TrueCrypt, BleachBit, and a few other things I'm not going to write about."

My take on that is that the author does not trust all the things he advises us to use, since he relies on other things he is not going to tell us about. Which means he is safe(r), we are not, and wont be, since he wont share.

Great. What use is all that then? None.

BTW, Just read that O2 UK are blocking VPN traffic.....
