Well, its definetely possible on activitypub. Every “app” built on the atprotocol takes data from a relay’s firehose and then indexes it and does all the algorithm stuff. There is a project (https://www.fediscovery.org/) that will let people build centralised apps with fediverse data. Although, I could just make an algorithm that looks for keywords a user may be interested in, in the posts database and show it to them, it just wouldn’t have every post to its disposal.
Algorithm control is what AT Proto offers that fediverse doesn’t
