That’s a very polite explanation and it’s not bad but I believe it’s not complete. The fragmentation is a strength, so they kind of contradict what they say. But in this case, .world keeps growing and it’s too generic. Iirc, .world got defederated by beehaw too. So it makes sense to me to move to a specialised instance where they will have much better reach and be discovered more easily by tech minded folks. They’ll be able to interact with beehaw too for example and since the instance is focused on tech, they won’t have to worry about other instances defederating them based on nsfw content or excess of memes which is turning a lot of people off.
