After seeing two Facebook posts of quite different length each having a "more" link that revealed only a few more words, I came to the conclusion that it has nothing to do with a clean layout and everything to do with the algorithm getting a stronger signal from the user that they're actually reading a given post, not just stalling their doomscroll for unrelated reasons such as an IRL distraction. If I want to see a little less of a certain type of post, but not to the extreme of unfollowing a given poster, I'll try to avoid clicking "more" in hopes of training the system.
