although this is unlikely to substantially and directly impact us and is a more immediate concern for Mastodon and similar fediverse software, we've signed the Anti-Meta Fedi Pact as a matter of principle. that pact pledges the following:
i am an instance admin/mod on the fediverse. by signing this pact, i hereby agree to block any instances owned by meta should they pop up on the fediverse. project92 is a real and serious threat to the health and longevity of fedi and must be fought back against at every possible opportunity
the maintainer of the site is currently a little busy and seems to manually add signatures so we may not appear on there for several days but here's a quick receipt that we did indeed sign it.
Who says it's "supposed to be [fully] connected?" Who gets to decide for everyone that no one is allowed to block, no instance is permitted to separate or shape its own view of the network? What's the difference between what you want and Reddit? One solid mass of "everyone must be mashed together at all times and nothing may be done to protect against harmful parts of the network" seems to betray the point of federation far more than some instance(s) blocking others or just straight-up forming their own clique (in the graph theory sense) or separate network.
Basically my thought here is: defederation is the point of federation or else it would just be distributed hosting.
This has always been the reason I don't believe in distributed models of social media. Federation also means defederation and that's good.
