That's because those half a dozen relays are Nostr's version of indexing servers. The vast majority of message exchanges come from global searches, because that's when clients interact with the most messages.

For checking follower posts and replying to conversations like this, Nostr has no need to rely on those monolithic servers. There are hundreds of options out there to choose outbox relays from. In fact, there's no reason why a person can't create a single user relay to host their own notes.

Does Pubky have indexers? Does Pubky have global search? It seems to me that if the government shut down the top few Nostr relays then the biggest change is that we would be slightly closer to Pubky. Is that the terrible fate we are supposed to be afraid of?

With your threat model, I think you would be better served thinking about moving from the clearnet to the darknet, not from Nostr to Pubky.
