I'm guessing for some genres it is ok to write without ever annoying anyone but what I think Kingsley Amis is referring to is to avoid bland, vanilla writing whenever possible. Your writing may never appeal to every reader but what if your intent was to annoy? Could this be your motivation to write in another voice.
