Not if it's set up right. This federation is the model, it just needs to be tweaked. Clear rules on instances that can talk between the lemmy and piefeds to the open source facebook and twatter and instagram type social medias. One account that can travel between them.
More than that, to have a clear set of rules for moderation, both in the instances and the general forums, and for violations to be appealable, and a final decision contested to end in a jury trial of users. To prevent the powerful from getting their hooks in, and to prevent the moderators and administrators being unjust. It's the only way to get the critical mass we need to have a viable alternative to these silicon valley parasites that are in thrall to big business and government.
Also in addition we need new sort of organizations, ones where innumerable groups can cooperate on what they agree on on general forums, as they see fit. Privately and publicly, where we can pool knowledge, funding, create businesses where maximizing revenue isn't the only concern in sectors where the private market isn't providing needed outcomes, finding and grooming and electing political candidates, pooling votes and collectively using votes and other actions to force poliiticians to adopt our positions over those of monied interests.
Monied interests cooperate on what they agree on, and if we don't do the same we can never counter-act them. We are stronger than the united greed of those interests, that is hurting itself long term to maximize it's short term profit. We just need the forums to work together. Federated systems are that forum, to remove liability from he whole for one thing.
