Is the Roald Dahl Thing "censorship"?
No - it is one good option in a tricky situation.
The Roald Dahl thing: We need to hold writers accountable, even iconic ones. His descendants volunteered to change the texts. No pitchfork mob here. The descendants were responding appropriately to a changing society in which they wished to continue selling Dahl’s books. That is surely one good way to handle this tricky situation.
