in my opinion it is presumptuous and narrow-minded and vaguely nihilistic to say that it's fine if everything written on the fediverse gets erased forever. we don't know what use what we say here will be to future humans, or even our future selves. given how deliberately destructively a huge % of twitter has been erased, directly and indirectly by its owner, it's clear that nothing inside a corporate walled garden should be expected to survive. it's up to us.
