You retain access to the original work, and I get a watered down version that's easier for me to read to my kids at bedtime. Feels like a win/win?
Why don't I have the same freedom of expression in your mind that you seem so intent on protecting on behalf of a dead guy?
But I don't, and that's the point.
Also, you can currently purchase every single Roald Dahl book on Amazon for at most ~$10, so in so many ways it's incorrect to say you lose access to Roald Dahl's original works.
"Original books to be kept in print following criticism".
Seems like that solves all of your issues…
Does it? If a library has a copy of the offensive censored one, they might not buy the original. There's only a limited amount of money available, every censored copy purchased means one less good copy.
If you want to write a book that doesn't call folks ugly, go knock yourself out. I'm all here for that and I support you. You may or may not find success, and that's life.
If you want to edit the words of a story because you find them unpleasant... if you want to censor an author after his death because you might sell more books... Then I find you ugly. You are willing to throw away content you disagree with, instead of tackling it head on, so both ugly and cowardly.
Where does it stop? What content is "you approved" in a way that we can all live with?
If we happen to live in a spot where those words are also owned, and we've decided that I don't have the rights to copy and distribute the original words because of the greed of Disney... then I find you both ugly and authoritarian in ways that are uncomfortable. I strongly dislike you.
