In a follow-up to the previous entry I'm posting a Democracy Now interview with Lavabit owner and operator Ladar Levison.
Levison made the difficult decision to shut down the encrypted email service, Lavabit, after an apparent bid by the U.S. government to gain access to customer data. As mentioned in the previous post, it's been reported that Lavabit was a service used by NSA whistleblower, Edward Snowden.
Also check out a Democracy Now interview with Nicholas Merrill, who operated a New York-based internet service. Merrill was the recipient of a "national security letter" that ordered him to hand over confidential customer info. He was also placed under a gag order - prohibited from discussing his situation. With the help of the UCLA, Merrill fought the gag order. Interview - here.
