So much for infringing upon their artistic expression. If it is fine for the airlines, then why should they mind selling an edited version to the common folk?

Because the copyright holder is the one that decides what is done with his property. If you wrote a book and someone decided to publish their version of your book and profit from it, would you allow that? Especially if they were cutting into your profit?

They aren't "publishing" a version. They are simply making edits to a version already purchased. It actually increases profits because every copy sold this way is a copy that would be unsold otherwise.
