Dahl was a transgressive writer also for his day - at least I've always had that impression. His macabre deliciousness and sharp wit are what makes his books so good—like an Edward Gorey for kids, but not too much for kids. So some of these edits are artistically consequential, the same way that the Bowdlers' "Family Shakespeare" was (https://en.wikipedia.org/wiki/The_Family_Shakespeare).
Things go in cycles, so I wonder if the Bowdlers will be rehabilitated. Probably not, because their specific motives are so anachronistic now. Also, their name has been a term of derision for 200 years and that's a black hole to get out of. But if you abstract away from the ideological specifics, the phenomena are remarkably similar.
