"Lavabit abruptly shuts down" [0]

The original poster believes that this case is apparently the reason for Lavabit shutting down. The issue as hand is that a proper search warrant has been issued for the email address in the title. Lavabit appears to have chosen to shut down rather than respond to the search warrant (or has responded to the search warrant, but chosen to shut down rather than have it happen again)
