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.
Well this comment section was an interesting read. Interesting how many comments still bend the discussion towards bashing lemmy.ml and defederating from it. People, it’s not even the topic of this post?
Also it seems like very few actually read the post beyond the title? The problem is not lemmy.world banning the piracy community, they have the right to do so, that’s how federation works. The problem is them making a promise to make announcements about such bans in advance, but they instead did it quietly in the background again.
