Durov's assessment of Snowden is unambiguous: what he did was brave, important, and revealing. The most significant lesson, in Durov's telling, was that people who appeared to be independent security and cryptography experts were actually connected to the NSA, promoting encryption standards with deliberate flaws that gave intelligence agencies backdoor access. The second lesson was that government, given the opportunity, always overreaches: 9/11 created a genuine need for a security response, but the response expanded far beyond what was justified, eroding the right to privacy on a massive scale. Asked which intelligence agencies he fears most, Durov gives a characteristically philosophical answer: they all can probably kill him one way or another, so the question reduces back to whether he fears death. The answer, as established at the beginning of the conversation, is no — or at least, he has trained himself to overcome that fear. He keeps in occasional contact with Snowden but has never met him in person and hopes to change that someday.
