That's game-over with the types of threats HN is concerned about these days.
Of course to some degree, the smartphone is so compromised in so many different ways that it's basically not even worth trying. Your SIM card runs code against you, the OS reports back in dozens of ways to 2-3 different entities, app stores can't be trusted, advertisers...
I think it says more about journalists' egos than anything else. Have you ever been happy with an article on a topic you have intimate first hand knowledge of?
There were a couple of talks that appear related to that topic:
* "Beyond the Tech: Building Internet Freedom Tools for Real People" <http://events.ccc.de/congress/2013/Fahrplan/events/5550.html>
* "The Internet (Doesn't) Need Another Security Guide" <http://events.ccc.de/congress/2013/Fahrplan/events/5538.html>Glenn Greenwald is the guy who broke the Edward Snowden/NSA story this year. He was invited to do the keynote address at CCC, and he gave us all many important things to think about. I strongly suggest you take the 30 minutes to watch the keynote, and gain your own understanding of the issues he brings up - this is vital to our future.
