No they should have to pick every time whether they want to be in follower mode or discovery mode. Dismissing concerns as “the angry mob” is richly ironic considering the entire objection is that recommendation algorithms seem precisely tuned to foster angry mob dynamics. So yeah it will make the angry mob happy because it will be removing the primary mechanism for inciting angry mobs.
People here know that they have finer controls (which are still not actually that fine and also don’t really make the parameters auditable). The problem is these settings are hidden away in places most people will never look. And also, I stress again, none of this is actually auditable because they treat these as some kind of trade secret special sauce and there’s really no reason society should feel obligated to support or enable this business model.
