As a result of this meeting and our review, the FSF and GNU have decided to relocate our IRC channels to Libera.Chat. Effective immediately, Libera is the official home of our channels, which include but are not limited to all those in the #fsf, #gnu, and #libreplanet namespaces.
On June 25th, at 10:00 AM EDT (UTC 14:00), we plan to forward any channels remaining in the #fsf, #gnu, and #libreplanet namespaces on the Freenode network to their corresponding ##fsf, ##gnu, and ##libreplanet counterparts. As per Freenode policy, channels with the ## prefix are unofficial “topical” channels, and accordingly, they will not be moderated by GNU or FSF staff.
Please note that the irc.gnu.org address, which has historically pointed to the Freenode network, will be disabled on June 25th, to give any users still connecting with this address sufficient notice.
Honestly, i wouldn’t say that people are switching away from XMPP in favor of Matrix… because i think most FLOSS projects never switched from IRC to XMPP to begin with, i don’t have proofs, but i don’t have any doubts, i assume that most projects switched from IRC to Matrix because XMPP was never an option to begin with.
