It’s called a federation. Its design is intended to give people options. To provide a diverse network of content that people can navigate as they see fit.
The internet can naturally do a bad job of facilitating good and robust conversations.
Federation is the only cure I’ve seen for social media … where separate but connected and navigable spaces can co-exist, enabling a discourse through contrasting biases and perspectives, for those willing to use the content that way.
Can’t stand a community or instance? Don’t subscribe. Or unsubscribe or block.
Instance defederation is an extreme action and requires extreme justification IMO. It reduces the size of the network and the value of the ecosystem. Especially for lemmy world’s size … it has a responsibility to support the network.
What some loud people find unacceptable is likely interesting to some quiet others.
Differing political “sides” or perspectives isn’t enough. Politics isn’t everything for everyone. Moreover, it’s exactly the domain in which a diverse array of content is most valuable and important … because no one has all the answers!
