Trailrunner7 writes with this snippet from ThreatPost:: "Silent Circle's decision to shut down its Silent Mail email service may have come quickly yesterday, and the timing of the announcement admittedly was prompted by Lavabit's decision to suspend operations hours before. But the seeds for this decision may have been sown long before Edward Snowden, who reportedly used Lavabit as a secure email provider, was a household name and NSA warrants for customer data were known costs of doing business. ... 'When we saw the Lavabit announcement, the thing we were worrying about had happened, and it had happened to somebody else. It was very difficult to not think I'm next,' Callas said. 'I had been discussing with Phil [founder and PGP developer Phil Zimmerman] over dinner the night before, should we be doing this and what the timing should be. I was looking at it from point that I want to be a responsible service provider and not leave users in a lurch. [The Lavabit announcement] told me I have to start moving on it now.'"
