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)

It is well known that secret services of unfriendly countries use material they can get as blackmail. The risk is not getting extradited to Russia, the risk is a Russian agent pressuring someone who works at (say) a defense company to do their bidding.

I'm not big fan of US politics at the moment, but still easily choose US spying over Russia. There is still some difference between these countries.

I'm more worried about electoral interference and stoking of social tensions than prosecution, personally.
