On Telegram you could always report messages from any group to moderators, this acts like forwarding. Private chats are still private too – although you could always report a new incoming chat to moderators by using Block > Report. Anyone can check Telegram’s open source code and see there were no changes.

The FAQ change only made it clearer how to report content on Telegram, including via DSA. The removed language was never related to content reporting.
