he twitt :
For 7 days Russia has been trying to ban Telegram on its territory – with no luck so far. I’m thrilled we were able to survive under the most aggressive attempt of internet censorship in Russian history with almost 18 million IP addresses blocked.

If you live in Russia and support free internet, fly a paper plane from your window at 7 PM local time today. Please collect the airplanes in your neighborhood an hour later – remember, today is Earth Day.
one resion is because of cryptocurrency because telegram want to publish ton and gram and wallet in telegram .so rusia prevented.
