The basic premise with algorithmic feeds is that users are lazy and don't do a lot of active discovery, so their follow lists tend to be pretty small. The algorithm can show them a mix of content where some of it is sourced from their existing follow/like graph (e.g. followed by someone you follow) and therefore likely to be interesting, and some is pushed on other less user-centric grounds. (E.g. in Twitter's case:…
Ok but that does not explain why you would actively remove content from their follow graphs. Sure, perhaps you can use the follow graphs to see what other stuff the user might be interested in and serve that, but why actively prevent the user from seeing posts that he has explicitly said he wants to see?
