You’re being intentionally obstinate. You keep implying that you can’t host your own relay, to which many PDSs (that also link to other relays) can’t link.

With bluesky, people choose what federations to join by selecting which relays their PDSs will join.

The analogy of geopolitical federation is cute, but that’s an analogy, it’s not actually what federation is when talking about technology. You seem upset that bluesky achieves federation with a different architecture, and idk why you’d be upset about that, or even care
