No. But as we all know, there is practically no firmware which can be trusted. I think the issue is always about measuring risk versus the threat level. Journalists that we train every day all over the world are always going to carry out high risk activities. The temptation is always to try to build a tool for the most extreme threat model and in the process, bypass the most common threats - leaving the average journalist with even less protection. Indeed, we increasingly find far much focus amongst our trainees on high level NSA Prism the stuff while little consideration of the basics - passwords, who has access to information in your own office, dealing with physical surveillance etc etc - all of which oir experience has taught us is far more common security hazard to journalists.
