You've hit the nail on the head. This used to be a "writer's" platform for "readers" and when Ev announced the introduction of these new "purchases" of Knowable and Projector he made it seem like they were going to be "enhancements." But, perhaps, enhancement isn't what he's up to. Perhaps Medium will be going in a TikTok direction where writing and reading are taking a "back seat" and then getting kicked out of the bus altogether.
