Why? There is a low chance of FSB successfully prosecuting you as western Citizen doing illegal/silly things in Telegram.
Big Five of other hand (UK, USA, AUSTRALIA etc) spy network are already working with your western government...
So I would rather be compromised in Russia with 0 chance of extradition there than non 0 to USA, UK GERMANY etc
(Let's say you are producing fake Coco Channel perfumes)
