Uh, I'm not sure it was actually 700. Not every channel with libera in the topic was taken over. It was mostly just those with a single #.
"I didn't beat all of them, just the ones that I thought showed /real/ disrespect?"
It's a abuse of trust. That's it. Any (other) commercial company trying to do the same thing would be in deep trouble.
So, definitely not in defense, just pointing out where the numbers came from. The ##* channel I've op'd for many years with hundreds of users has had "libera" in the topic for a while and has not yet been taken over. But we are moving regardless.
So I assume that advertising Libera is not (yet) enough to be taken over. Taking over channels that declare themselves closed (and redirecting them to an unofficial channel about the same topic) seems reasonable, tbh.
