ChainCatcher news, according to CNBC, former Russian President Dmitry Medvedev said that Telegram CEO Pavel Durov fled Russia and thought he would never have to cooperate with security services abroad. This was a misjudgment.

Medvedev often uses Telegram to criticize the West. He said Durov wanted to be an "excellent 'world citizen' and live a good life without a motherland."

"He miscalculated," Medvedev said. "To all our common enemies, he is Russian - therefore unpredictable and dangerous."

The Russian Ministry of Foreign Affairs said it had sent a note to Paris requesting a meeting with Durov, even though he already has French citizenship.
