Federation is absolutely necessary to scale a system that needs discoverability and access control for heterogeneous data types from unrelated producers. There is no way to scale it in a centralized manner without having insanely large and complex data governance. I wish the author had prefaced with the context and scope. It seems like this is really referencing something like a decentralized twitter. So sure, in the context of the author maybe that's true but it's clearly generalizable about federation.
