Telegram is giving away FREE Premium subscriptions! All they need from you is to use your cell phone as a relay to text out their OTP codes! And the recipient of the OTP sees your phone number! What could POSSIBLY go wrong with this deal?
PLEASE don’t use Telegram! I personally recommend Matrix as it’s totally FOSS, you can self host, there are tons of front end clients to choose from. Or even use Signal. I have my own issues with Signal, the fact they don’t allow third party clients, you can’t self-host, they have a proprietary shim in their stack that only they know what it does, they were pushing crypto, etc, but at least Signal is better than this garbage.
Signal is pretty broken. A chat app shouldn’t require a SIM card & an iOS/Android device just to create & maintain an account (too bad Linux or KaiOS users or folks that otherwise don’t want a smart phone). Multi-devdice setups seem to have issues. The desktop app being Electron is a waste of resources. They still don’t want to support UnifiedPush while highly encouraging you download the app from the Google Play Store & send notification data thru Google-controlled FSM. There’s also the missing history of the server code which is probably has something to do with US intelligence injecting code.
Is it better than a lot of things, sure, but it should be put on a pedestal nor seen as exemplary for private chat in UI or philosophy.
