This isn’t the first time I have proposed this, but the pushback leads me to believe the owners do not want to relinquish power to the users. Lemmy it seems, is a community for owners. The interests of instance owners and their delegates come first.

That is true because admins pay for the servers and are legally responsible for the content they host. However anyone can quite easily become an admin, the hosting cost for a single user instance is very low.

This is not that big of a problem. A third party can always make a bootleg version of metacommunity post viewer. Lemmy can already view posts across all federated instances using “All” tab, so all that would be needed is some method of meta labelling of same (not similar) communities across instances and to be able to view unified communities under such tags, and this tagging be done appropriately by all instances’ admins in synchronisation, ignoring their personal and ideological differences.
