Telegram outright refuses to comply with any records requests not related to child abuse or terrorism, and even those they often delay and only release phone numbers and IP addresses. They have the data and basically use grand scale legal gamesmanship to avoid data requests. See https://www.spiegel.de/netzwelt/apps/telegram-gibt-nutzerdat... or even their own official policy https://telegram.org/privacy?setln=it#8-3-law-enforcement-au.... If you actually have the data to turn over you can't do this legally.

Durov's exile is also somewhat tenuous: https://tjournal.ru/tech/52954-durov-back-in-ussr https://lenta.ru/news/2017/03/20/durov/

This is sort of forgotten now but there was the time where they censored the Smart Voting bot.

I don't think going after Durov personally is justified, and the charges should just be contempt of court if anything. But I don't trust him.
