So why doesn't he share with everyone? If he's willing to shut down his service in the spirit of security, why not expose details in the spirit of transparency?
I can't imagine all of it would be subject to a lawsuit.
I very appreciate his actions, what he has felt able to say publicly and his dilemma in general. Part of me wants to call him a coward, but I can not say I would do better. I can't criticize. What this does show is how brave and "heroic" people like Snowden, Bradley, and the like really are.
What would be interesting is to see if he tries to get his story heard via routes acceptable to government, and if so, what happens.
Where have you been all this time? Have you not read the news recently? Basically every US IT company is being NDA'd and backdoored/taped. Lavabit is the first one in choosing a different option: closing the business.
