For one thing, in the original novel, the Oompa-Loompas are a transplanted tribe of African Pygmies.I'm really not a fan of censorship and editing. Maybe it was all of the changes I have experienced with the original trilogy Star Wars films that put me off.
But I did recently learn that there were changes between 1964 and 1973 made to Charlie and the Chocolate Factory. I now really want to read the original version.
I'm totally against censorship or so-called "sensitivity" revisions of children's books or anything else.
