Considering how the freenode takeover was done, I don't believe the statuquo is a viable option here. This is below the belt and I don't think they deserve our userbase. Maybe this is a grayzone and this is borderline legal, as a FOSS community, we have the responsibility to take a stance against this kind of behavior by dropping our support to the new freenode.That's the least we can do.
I understand that moving away from current freenode to either libera, or whatever other medium the community will choose is going to be a hassle to everyone. We're going to waste quite a lot of time to move everything and transition. It shouldn't be rushed if we want to change medium. We need to evaluate options, maybe we should vote, and/or deploy stable infrastructure if necessary.
I still believe that moving to libera should be quite trivial for most of us and should probably be done ASAP and from there we can decide where we want to go next.
