The Fedipact is deeply regressive. It follows web2 logic, meaning, it treats the arrival of Meta, like it delt with problems in web2: it uses defederation like cancelling - although cancelling heavily depends on the network effects of social media, most of which Meta owns. While in web2, it was possible to isolate people that one was at odds with through this, it doesn’t work like this here, because the cost to do so are much higher, when in web2 they were zero. You are basically trying to cancel the thing that gave you cancelling. This is why the Fedipact will be neither effective against Meta, nor other similar problems in the future. Most of this stems, I think, from the fact that the Fediverse is overwhelmed with the situation and doesn’t have a better solution, and that it hasn’t really understood network effects and how they work in the new, federated social web; so, it falls back in old, regressive behaviour.
