Then some people might not follow you because they like to be more private about their tastes. Or alternatively, they might follow you in order to send you a positive message, but then they might actually not enjoy having your memes displayed on the Followed Users page.
I suppose this is why Facebook has multiple ways of following/friending/ignoring someone now.
If we really want more functionality I suppose we could add options for each follower you add. Checkboxes to enable displaying on the other person's profile, enable their content in your Followed Users page, and any future options we want.
