Bluesky is built on atproto, which is designed to be "locked open" in a way that can't be rescinded. That was a core design constraint.

VCs funded Netscape which did more than any other company to launch the web and they made a lot of money without having to destroy the ideals of the web.

The PDSes (personal data servers) can be independantly hosted, but Bluesky itself indexes and presents the messages these servers contain in their social-app. Bluesky also maintains the directory of these servers.

Anyone else is also free to run these services (app views, relays) and a few people already are doing this.

An atproto PDS is like a structured-data blog hosted on a web server. Anyone is free to index, relay, and render the data.
