@BeAware I think the misunderstanding is because you're looking at it from the ActivityPub perspective and expect it to work in a similar way, but it doesn't, but that doesn't mean that it's worse.
You're asking about connecting to Bluesky servers, but there's really two different things here that I think are worth separating:
1) when I have my PDS, do I need to contact any Bluesky servers in order to communicate with someone else who has a PDS?
2) do our posts end up on Bluesky servers?
