You seem to think that an artist by default creates art that is purely impersonal and unconnected from who they are and then manipulatively goes back to add stuff that you don't like. But it's the other way around. If the work is divorced from who they are in favor of consumer needs, it's just craft. Art is inevitably personal. So what I think you're really asking for is for people to hide who they are if you don't like parts of them.
