With all due respect, it sounds like you are not familiar with Bluesky.

As far as I know, the only proprietary code is the single Discover feed, which every user can un-pin from their feeds. My assumption for this being proprietary is so that it cannot be gamed. It could be for a darker reason, I suppose.

However, this is a feed that I use maybe 10% of the time. Aside from the Following feed, I have curated a bunch of my own user lists and 3rd party feeds. I am able to pin these to my feeds list. This is where I spend my time.

Aside from that one significant feed, yet small aspect, literally every other part of Bluesky is open source. This includes client, server, moderation system, and protocol.
