But I feel like it misses the point. What about a service where you can design and use your own "algorithms", and it's built into the platform?
Such a platform would have thousands of algorithms, but none of them designed for chasing money or engagement, just different preferences. But Mastodon could still claim "We don't use The Algorithm and is therefore better than other places" while a platform with custom user-owned algorithms could get the best of both worlds.
