I would 100% make the same argument. The problem is changing an author's work without their permission, and failing to indicate that. As others have said, if this were marketed as "The bowdlerized Roald Dahl" in clear print on the cover, it would not disgust me in the same way.
> Would you make the same argument about a modified Shakespeare performance?
It is typically clear in these cases that Shakespeare is being modified.
