Speaking of out-of-network content, btw, it's also what shaped Bluesky's architecture to a substantial degree. It was built from the outset on the assumption that people need to see posts from outside of their network, that it's an essential non-negotiable property that this system must have.
That's the fundamental difference between Bluesky and the fediverse. Bluesky tries very hard to emulate the current commercial television-like passive-consumption entertainment-ass social media. Fediverse, on the other hand, takes an old-school user-friendly approach where you see the posts from people you follow, in the order in which they were made, and nothing else at all. If you really insist on seeing random posts from people you don't know, there are local and federated timelines.
