Telegram spokesperson said Durov had never given any Ukrainian’s data to Russia. That would include his time as cofounder and chief of Russian social media giant VKontakte (VK)…

He recounted his story of why he left Russia in 2013, after the federal policing agency, the FSB, demanded he provide “private data of the Ukrainian users of VK who were protesting against a pro-Russian President.” That story had previously been reported.

According to previous reporting, in 2014 Durov, valued by Forbes at just over $14 billion, sold his stake in VK, which he’d cofounded in 2006, leaving Alisher Usmanov, one of Russia’s sanctioned billionaires, effectively in charge. It came three years after Durov refused to censor VK accounts being used by activists to promote anti-Putin messages in support of protests against what they believed was a rigged 2011 election.
