To anyone bemoaning BlueSky's lack of federation, check out Free Our Feeds.
It's a campaign to create a public interest foundation independent from the Bluesky team (although the Bluesky team has said they support them) that will build independent infrastructure, like a secondary "relay" as an alternative to Bluesky's that can still communicate across the same protocol (The "AT Protocol") while also doing developer grants for the development of further social applications built on open protocols like the AT Protocol or ActivityPub.
They have the support of an existing 501c(3), and their open letter has been signed by people you might find interesting, such as Jimmy Wales (founder of Wikipedia).
