Except we're not talking about people being critical of their writing style, their character development, or pointing out plotholes and plot contrivances, but about allowing a vocal few to dictate the direction and events of the story.
If certain people don't like a certain character and would want to see them get killed off or otherwise removed from the story, DPC should not ever listen to those people if he doesn't plan on doing that because it is not up to them to tell him what he should and shouldn't do with his characters. The same thing if people start asking for some kind of sexual kink like BDSM or incest; if DPC doesn't plan on doing it, then he shouldn't do it just because some people might want it.
