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.
You seem to have a fundamental misunderstanding what IRC is. It is not something like Matrix or XMPP or Signal or whatever. It is just a convenient & standardized way to have a simple public chat somewhere. If you want you can have a simple link on your website saying “click here to join with your preferred XMPP or Matrix client”. Works perfectly fine with IRC as the base and some bridges running on the server.
