I agree that security should be taken seriously, with care and caution, and that users who ethically need to be aware of potentially fallacious assumptions about the usage of a device should have the capacity to easily find that information.
It's fine if you think this is an unreasonable conclusion to draw based on the evidence; you're entitled to your opinion. But the question is, do you feel comfortable with the possibility of people going to jail or dying because they didn't understand the security tradeoffs that this app makes? I think it's because some of us see this as an extremely real possibility -- particularly given the frankly ineffective security practices described here -- that you're seeing so much backlash.
