Telegram is indeed not E2E encrypted, and messages sent to/from bots cannot opt into E2E; but would you happen to have a citation handy for more information on these logging servers in Russia you speak of? Thanks!
"In August 2014, SORM-2 usage was extended to monitoring of social networks, chats and forums, requiring their operators to install SORM probes in their networks."
Telegram is not hosted in russia, but you are right, trusting telegram, is trusting ceo Pavel Durov and hist good intentions, much better than any big tech, but not even close to a proper e2ee
