I dont know why people bring up telegram. A vast majority of chat messages is sent directly in the clear to Telegram servers. Telegram can spy on your conversations. If they can, anyone can. It is NOT an encrypted messenger. It is a crappy plaintext messenger that has an encrypted feature that nobody uses. Also - Stop using telegram. IT IS NOT ENCRYPTED LIKE YOU AND YOUR FRIENDS THINK IT IS.
It does have secret chats, which are supposed to be E2E encrypted
China will glady sell the Indian government GFW technology.
