#Telegram always smelt like a honeypot to me;
* centralised, tick (like Signal)
* encryption doesn't work for groups, only 1:1, tick (like Signal)
* opt-in E2EE for 1:1 chats while heavily promoted as "encrypted messenger", tick (unlike Signal)
* Roll-Your-Own cryptography, tick (maybe like Signal, but crucially...)
* no source code published for server, so no independent auditing of cryptographic primitives or implementations, tick (unlike Signal)
I can't fathom why anyone uses it.
