Telegram is not encrypted speech! The connection to telegram server is encrypted (with home baked cryptography - not a good idea especially in chat protocols), but the data is not end to end encrypted and Telegram servers see plaintext. There is an option to do a sort of home cooked encrypted one on one chat that no one uses, but any groups/channels are just a goldmine for whichever intelligence agency gets their fingers on it. If you want encrypted: signal, simplex, ... Here's a comparison: https://juraj.bednar.io/en/blog-en/2022/05/03/encrypted-messengers-comparison/ Here's an explanation on why I think it matters: https://juraj.bednar.io/en/blog-en/2022/04/29/encrypted-messengers-how-to-communicate-privately/ Also: Nostr is also not encrypted.

Also, ironically, making it encrypted would help him avoid jail. (I don't cheer on him being arrested, that's a horrible precedent). Signal does not see groups, membership, content, ... They encrypt to protect the users, but also themselves. They can't analyze messages if they contain drug trades or child porn, because they are not in business of storing messages, they ship around encrypted blobs of data and they can't tell their meaning even if they wanted to. SimpleX goes even further - they don't operate infrastructure, anyone can run a relay. They are in a business of writing user interface for end to end encrypted chat protocols. Users use servers operated by third parties, that also don't see the content, in this case not even user identifiers (there are none on SimpleX). Each connection looks different, so you can't even write a proper court order, because it's very hard to identify what user it concerns.
