The first problem with Telegram is that it's not full e2e. Only the private chat function is end to end encrypted, all group messaging is not.

The second problem with Telegram is that it's not truly open source. Only the client is open source and I recall (correct me if I am wrong) that the client code is not even up to date with the deployed apps in production, which seems strange to me.

The third problem is that Telegram are using their own encryption and authentication algorithms rather than using academically reviewed techniques.

The forth problem is monetization, after so many years of operation with no ads or obvious income stream from consumers it makes me question how it's even operating.

Other than these concerns, telegram for a daily casual messenger is great. The app is better than whatsapp and is cross platform.

To address my problems/concerns with telegram I recently tried "Wire". Which seems to operate more transparently and securely, whilst also having excellent cross platform apps.

The first and only problem with Signal, for me, is that it’s unusable. See my other comment above. There’s no point touting security benefits if the app and platform are not meant for the masses and cannot be relied upon. FWIW, I’ve tried Signal many times in the last few years, but one thing or the other forces me to abandon it.

I have tried Wire and like it. But it too misses in the chat sync across devices sometimes (even within a day or two of the message being sent).

Yes wire isn't perfect, but I think that if more people used it and more organisations paid for it, then it would become better over time.
