It’s precisely because iMessage and Telegram don’t treat the desktop as a second class afterthought that I use them for messaging instead of Signal.

* Has no E2EE for desktop clients
* Has no E2EE for groups.
When security is an afterthought, no convenience feature matters.
This is really confusing they have two official desktop clients for MacOs.
