(Submitter's note: This is mainly an "excuse" for people to talk about the Freenode/LibraChat situation, as it seems very tech-interesting and I'd love to hear more as well as talk about it.)

This had originally been decided a few days earlier, and was dramatically accelerated as a result of the above: https://www.gentoo.org/news/2021/05/23/Moving-to-Libera.html [gentoo.org]
For those interested, a fun executive council meeting is noted: https://projects.gentoo.org/council/meeting-logs/20210523.txt [gentoo.org]
