Lavabit, the security-conscious email provider that was the preferred email service of NSA leaker Edward Snowden, has closed its doors, citing US government interference. § "I have been forced to make a difficult decision: to become complicit in crimes against the American people or walk away from nearly ten years of hard work by shutting down Lavabit," founder Ladar Levinson said in a statement posted to the company's homepage on Thursday. "After significant soul searching, I have decided to suspend operations."
