Hmm, can you clarify which part(s) made you think that? We made sure to put it in two places that the page was specifically for Patrons (images below).
Oh, yes, we unfortunately can't do anything to remove that. We had to set a price, or else the files would be free for anyone to download. As far as we're aware, there's no way to set the files so that only Patrons can ever download them, so unless itch.io gets an update, there's nothing we can do about that.
