Because the books came to be loved in their original form, and in that form were an expression of Dahl's creativity. Because the changes take place silently and impart a sense of moral value that wasn't originally present. Because in attempting to paper over things that we object to in our past, we lose the opportunity to talk about them and learn from them.

It's not just a knee-jerk reaction to 'wokeness' to be upset by this kind of thing. My opinion is that people _should_ be upset by the presumption of some faceless editor that they're too stupid and base to apply their own judgment to the original text.
