“An encrypted email service believed to have been used by US leaker Edward Snowden shut down on Thursday apparently as a result of pressure from US authorities. Lavabit owner Ladar Levison posted a message at the website telling users that the he was pulling the plug on the secure email service launched in Texas nearly a decade ago. Levison lamented that he was barred from sharing details of what prompted Lavabit’s demise. US law allows national security officials to make requests to companies that come with the caveat they must be kept secret.”
