[EDIT] My point is, from King's perspective, this likely looks like "you're here and making $X over what you would if you just relied on your fans to repost all your stuff on here for you, we're making $Y more than we otherwise would because you're here, plus we've given you this blue-check thing to solve a problem we have, but now $Y isn't enough and we're going to make you pay money to keep participating in this program that exists to solve a problem for us."

You can see how, unless $X is pretty big, someone who's already rich might say, "well fine, fuck you too" over such a thing.
