True. I would not want anything published without my permission, that is certain. I have personally written a few things, never published them, and already destroyed the copies!!!
But there have been a lot of works that have been published posthumously, and certainly against the will of the author / artist, that are valid works that stand on their own. Or, if they are not complete (fragments), they still can provide a bit of insight into the artist. (Note: I am deliberately abstracting, because authors, musicians, painters, etc., all face the same situation.)
I agree - this is a grub for money by the publisher, and it would be criminal for the reader to buy it / be tricked into thinking that it was a final completed work as intended by the author. But the drafts may still stand on their own as fragments, and it would be the job of the reader to understand it as such.
