It has happened before Stanley Kubrick, decided he didnt like Clockwork Orange and pulled it from publishing and it stayed that way for quite awile. and yes while the authors online can and have remove their works of fiction, The material they publish is theirs and to say that they cant/shouldnt delete their propert, is so very wrong and I would think that this is why a lot of them have deleted their property or they have become mainstream published and have to remove all copies o ftheir work.
just my lil 2 cents
