Bluesky also offers both composable moderation and the ability to choose your own algorithm.
Bluesky claims to offer the ability to choose your own algorithm, but this is not the same as actually doing it. Because Bluesky is not truly decentralized, and they control the backend where the algorithm and content sorting software is actually run, there is no way to verify if Bluesky is actually using the algorithm the user desires for them to use.
Although I don't think Bluesky will be lying so early, I fear in the longer term, enshittification will get to them, and that may manifest as users having the illusion of freedom, but actually having even less choice then what they started with on Twitter.
