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.
It’s definitely not ideal to be this centralized around lemmy.world. But it’s also nearly impossible to prevent some amount of centralization, especially at our current size. With only 50k active users, we don’t have enough people to sustain activity if things were more spread out.
It’s still so early. If we get to 500k or 5M users, things will naturally get way more decentralized. A year ago, about 70-80% of the whole network was basically centralized on lemmy.ml. I dont have the exact numbers because I wasn’t here yet, but looking back at the stats there were only a few thousand active users at that time and the vast majority were on lemmy.ml
Now, only about 40% of the network is on lemmy.world (20k/50k users). I just think there are natural incentives that will continue to push us in the direction of decentralization, but we haven’t quite reached the tipping point where that starts to happen.
