This is because it’s emulating Reddit, and operates in the same ways, cultures, and countries as Reddit does.
From bad mods and bans, to niche communities, to the brigading and politics. From rating posts, avoiding discussions, and responding with meme floods.
Lemmy will merely reproduce all the negativity, politics, and everything else we hate about Reddit …and it’s already doing so.
[EDIT: As you can see in the comments, full of people agreeing Lemmy will also be toxic in similar ways].
They don’t even want people to browse it without logging in any more. I’d cruise by occasionally mainly to remind myself why I left, but I can’t any more, so I don’t even bother doing that. Reddit is dead.
