tl;dr :
- Hexchat IRC client app development stopped
- Linux Mint team was building IRC client to replace Hexchat
- The team tried Matrix and liked it
- Linux Mint’s communication channels are moving from IRC to Matrix
- The desktop app will be named Matrix to avoid confusion
It’s the easiest to use.
While this is true IMO, it’s needed to say that the redesigned Discord mobile app is complete shitshow.
