There are different sides to security.

Telegram openly does not have e2e by default.

What it also didn't have that I think Signal at some point had was:

- a bug that sent photos(?) to persons without you asking

- a rather nasty vulnerability that let people send you a message and pwn your desktop environment

For some reason a large subset of HN is like E2E or nothing. But I remind folks that except in very particular cases, all email is available to one email provider or the other.

Same goes for banking etc. But for some reason according to HN my postcard level communication with my family demands I use a system with a tenth of the usability of Telegram.
