Telegram's backend is proprietary software and they (very similarly to Discord for example) can just decide to read your chats whenever they want. It's even worse then WhatsApp in this sense (at least as long as you trust Facebook that they actually encrypt your chats, again, there is no way to know if it's proprietary software).
Okay just element and signal then?
SimpleX looks neat.

And yet no one was able to crack it.
