Ladar Levison, 32, has spent ten years building encrypted email service Lavabit, attracting over 410,000 users. When NSA whistleblower Edward Snowden was revealed to be one of those users in July, Dallas-based Lavabit got a surge of new customers: $12,000 worth of paid subscribers, triple his usual monthly sign-up. On Thursday, though, Levison pulled the plug on his company, posting a cryptic message about a government investigation that would force him to “become complicit in crimes against the American people” were he to stay in business. Many people have speculated that the investigation concerned the government trying to get access to the email of Edward Snowden, who has been charged with espionage. There are legal restrictions which prevent Levison from being more specific about a protest of government methods that has forced him to shutter his company, an unprecedented move.
