Telegram has various issues for the privacy concerned, namely that group chats are never E2EE and 1-to-1 chats are not encrypted by default, among other concerns[1].
Also Telegram is not open-source.
Also Telegram did some shenanigans with cryptocurrency a few years back[2].
Telegram does have better UX than Signal though.

- lucideer 6y ago> Telegram is not open-source The Telegram apps are GPL. Their server is (afaik) closed-source, but having an open source server implementation doesn't mean much for a centralised service without any server-switching support anyway, so no effective practical difference to Signal here in that regard. The E2E situation on Telegram is poor however.
- fastball 6y agoI think the two things (open source servers and E2EE) dovetail together. If the E2EE situation is poor, what is happening on the backend with your data becomes more relevant.
