And once you’re the biggest game in town, people will optimize for you (just look at SEO and Google Search). It won’t matter much that people using the network can freely choose a different algorithm, just as it doesn’t matter much on the Web that people can choose a different search engine. And the more I read about BS’s protocol, the more I think this is done on purpose.

Why? Because it allows BS to pay lip service to decentralization, without actually giving away the power in the system. After all, BlueSky-the-company will definitely be the first to start indexing BS-the-social-network posts, and you can bet Jack has enough money to throw at this to get the needed compute. I guess decentralization is a big thing lately and there are investors to scam if you can farm enough users and build enough hype fast enough!

Of course, fedi could also have some search and discovery algorithms built on top. Operators of such algorithms (there had been a few attempts already) would also benefit from being first and going big. But their potential power is balanced by the power fedi instance admins and moderators have (blocking and defederating) and by the fact that fedi is perfectly usable without such algorithms. And by strong hostility of a lot of people using fedi towards non-consensual indexing.
