Insofar that I understand the issue, Andrew wasn't the one running a large community, he was the owner of the company holding the domain used by that community. The ones running the community were the oppers, who have since migrated to run LC.
No FOSS project has ever had any particular obligation to keep their IRC presence on Freenode, and migrating from one IRC network to another has always been a pretty standard thing (if uncommon for any given community).
These communities don't belong to Lee or to Freenode, and acting like moving to LC or any other network is somehow a violation of any reasonable IRC policy is just ludicrous. Any network that had a policy that that was in violation of is not a network I would ever want to be part of a community on: it's draconian and entirely self-serving.
And now "freenode" effectively hijacked established community centers, changed the locks, sometimes for the very "crime" of discussing whether to move... or stay. A lot took a wait&see approach, some were more decisive and used channel flags to prevent people getting lost, thinking they got official org channel while arriving in a dead one full of lurkers that forgot to kill a ZNC somewhere.
Not to say this is the same situation here as from what I understand, the guys who did the most work are moving to LC.
I just hope the same thing doesn’t happen to LC down the track, if it ever does, it will be an interesting case study of how they react.
But yes, looks like LC is now the home of IRC and for the foreseeable future should be drama free.
