If you want your timeline to be just a chronological timeline, you can also subscribe to that feed and delete all others. Bluesky isn’t Threads, no one is forcing any algorithm on you that you don’t want, this is part of the decentralized nature of Bluesky.
Also, I don’t think there is a clear line between “algorithmic” and “non-algorithmic” social media. If you use Mastodon with the Mammoth app and its “For You” feed, is it algorithmic or non-algorithmic? If I sort my Lemmy timeline by “hot”, do I not use an algorithm?
