@wolfi I would argue that the issues is not the tech but the: dealing with different social groups of varying views.
And I am being quite soft in that description as there are groups that on the complete opposite side.
What federated social media does, is it allows each group to have it's own rules, setting up their instances under their rules, instead of one company to set their rules for 400 million users.
But even on the birdsite those groups do not come together to talk.
