Pavel Durov, the founder of the Russian social network VKontakte, or VK, has resigned as chief executive after a seven-year tenure, claiming he was no longer able to defend the network’s founding principles. Durov‘s departure was not unexpected — at the end of January, he sold his remaining stake in VK after a surreal chain of events in 2013. Having already given the finger to Russia’s authorities over censorship requests in 2011, Durov was accused of driving over a traffic cop’s foot.
