The changes all look fine to me, and many of them probably make me more likely to continue reading Dahl books to my kid. I mean, none of the old language would stop me in my tracks but it adds up. There's plenty of options and I'm always picking the ones that I find the best, in many cases having a bunch of outdated language will cause me to pick something else next time.
What are you going to do with all the old books?
The replies about burning them are incredible when my post only said I'm less likely to keep picking the book up.
