Telegram has full access to all of the content of group chats and regular one-to-one chats due to lack of end-to-end encryption. Their opt-in secret chats use homegrown end-to-end encryption with weaknesses. Deleting the content from the app likely won't remove all copies of it.

Telegram's CEO, Pavel Durov, was arrested for not engaging in content moderation for various governments/intelligence agencies. This arrest is gross.
Simultaneously, Telegram isn't a private messenger. They have access to all group chats & regular 1-1 msgs unless using secret chat that is not enabled by default.
Who gets access to this now?
