The freenode situation is a little complicated, but we moved our IRC presence to the new Libera.chat systems a few days ago due to those events.
Today the new owners of freenode responded by removing our control of the #ioquake3 and #iodoom3 channels which makes it pretty clear that sticking with Freenode would have been a mistake. they even removed the ability for us to let people know what was going on.
Our new Libera.chat #ioquake3 and #iodoom3 IRC channels and Discord channels are bridged, and those are where we will provide discussion and support for those communities instead of Freenode.
