This has happened once before and they reversed it. But they said this last time too:
The discussions that have happened in various threads on Lemmy make it very clear that removing the communites before we announced our intent to remove them is not the level of transparency the community expects, and that as stewards of this community we need to be extremely transparent before we do this again in the future as well as make sure that we get feedback around what the planned changes are, because lemmy.world is yours as much as it is ours.
If I may ask, why still use .world then?
Great question, see when instances have management level disagreements like this there really isn’t any purpose to using their communities from a remote account.
Unlike a lot of people who “migrated” I realize it ultimately doesn’t make a difference using these communities from a remote server because they are controlled by this one and ultimately will be affected by defederations and bans. So I only migrated my non-lemmy.world subscriptions to the other instance accounts and left the local ones on this account.
