Seems more like an attempt at woke-washing that backfired because of the negative public response.
I read this as: editors are changing just some words in order to save Dahl, who should be banned completely. And Salon author calls their own stance “against censorship”. Hm.
Based on what?
As I said on reddit about this:
Warner Bros. have done fine with the pre-amble to their older cartoons that says something to the effect of "yo, this was written back when attitudes were different, they were shitty attitudes, but to erase them is to pretend it never happened."
A similar preface in the books would have worked much better, but wouldn't give you any amount of PR like this.
