The highest purpose of all communication systems, is the increasing of consensus among humans and their societies. The exchange of ideas between person and person, until one agrees with the other, vice versa, or something in-between.

More consensus, allows more secular decision making, furthers co-operation, and therefore increases the rate of advancement of our species. You can't achieve this by putting everyone in their own box with their own LLMs, which will only generate content in response to the occupant of the box. You're likely to end up with each person pulling in a direction of their own hallucination enforced chat session.

Modern systems often do the opposite of increasing consensus. It categorizes and divides us, avoiding confrontation and the exchange of ideas. Amplifying the insane, instead of challenging them. Affirming, not correcting. Modern mainstream social media, several other information technologies, and your misconceived notions of how the fediverse works, must be done away with.
