I teach literature to college students that was published 100s of years ago, so I'm very familiar with the fact that norms constantly change and that reading literature that reflects different worldviews and different mentalities is enriching and intellectually challenging. I'm also aware of the fact that texts go through multiple editions for different reasons and we need access to all of those editions in order to understand them fully from a scholarly perspective. The changes that are being made to these Dahl editions are being made with the permission of the copyright holder, so that's their decision - it's not been made by a committee of the politically correct. It's therefore more accurately described as revision, rather than censorship. It may well be of interest to future researchers on children's literature, but I don't understand why it's been seen as indicative of the downfall of civilization.
