The man who made that video is annoying. The story he read out was from the twits by Roald dahl, it was a few years back that those changes were made. Dahl was a great author but wasn’t a very pc person , his family have had to apologise for his anti semitism. So whoever is in charge of his works wanted to make them more modern and less insulting which misses the point of Dahl but anyway. They’ve done it with Enid blyton books too. In one of hers they have a dog called the n word so probably more necessary with her work lol.
All amazon have done is update the digital edition to the match the latest edition. There’s a million things to hate Amazon for you don’t have to make things up. And also if you want books that can’t be altered buy a paper book, you own them and they don’t run out of electricity.
