What proof? Do you want me to give you links to Russian laws that oblige all distributors of information to register in a special registry and provide encryption keys to the FSB?

I live in Russia and I know all the laws, the ECHR ruling will not change anything, Durov is still leaking correspondence to the FSB.
I read this article and there is a lot of untruths, for example that Telegram was able to defeat the Russian government by simply changing the IP address, that Telegram is operating outside the law, not following Russian laws, not giving out encryption keys and not cooperating with the state
