I'm not an active Wow Addon dev so take my opinion with a grain of salt, but I'm active in Sailfish OS (as developer at Jolla), some foss projects when needed at work and in Arch Linux.

This is my personal opinion but IRC still has the lowest barrier of entry, it does not track users in any way. runs on almost everything and is standardized so it does not depend on any operator, so no issues when stuff like this happens again.

As a dev it is very helpful that I can just /join on a particular channel and get help or contribute.

All this is not possible with discord, it creates all the same potential issues and more. Discord is centralised proprietary and only allows access with their client. If you want a more modern client without a bouncer users can join via matrix.

A possible alternative is OFTC which is not operated by the same staff from Freenode and is more established.
Some FOSS projects like freedesktop.org, qemu and GCC have moved there or where there before.


EDIT: Seems like some already joined #wowuidev on Libera, I checked OFTC there are none there so far.
