I suspect this was always the plan.I'm glad Puffin books resisted and left the books in tact.
Morally people have no right to change other peoples works. If they don't like it then just ban it. But we know they won't ban it because they know the reaction.
This whole mind set is the same as those that think talking to someone they consider racist, xenophobe (any other ism or phobe) etc person means that you automatically will be seduced by their opinions. It's a very weak mentality that is being taught. It's teaching kids to be victims, and infantilizing the rest of us adults.
It gave them a massive amount of free publicity for the upcoming "classic" Dahl books....
If that "classic collection" comes out in time for Christmas you can be fairly certain it was planned from the start, as the current lead time for new editions is about 6-9 months from what I understand.
