Here's a new scenario for you...
A guy named Jim walks into ABC Publishers' office with a book in his hand. Although this is Jim's first novel, he thought of the story and wrote it all on his own. The publisher agrees to read through the novel and after finishing it, he looks at Jim and says, "This is a great story, but I have to make some changes before it'll sell."
Jim allows the changes to be made, publishes the book, which he proudly stamps on the front, "Author: Jim."
Now... what you're proposing is that because the publisher made changes to the book, they should change the author's name to ABC Publishers and that ABC Publishers should have the right to sue Jim over ownership of the book.
If you still want to stand by that statement, you're welcome to... but you'll look like an idiot.
