Ask HN: Whatever happened to Paranoid Linux?

Cory Doctorow described in brilliant detail the fictional distro Paranoid Linux in his novel, _Little Brother_. "Paranoid" fully protects its users: encrypted communication and Tor by default, continual network chaff, etc.

Why isn't this in wider use?

There is no distro called Paranoid, but there are other security-oriented distros like LPS and Tails http://www.makeuseof.com/tag/linux-distros-paranoid-secure-distros-si/

Yet none is widely known and in wide use. Not even HN chatter talks a lot about these.

Why?

Does no one really care about security? Do these distros have usability or security flaws? Is it just a lack of marketing?
