It's not so much that there are edits, but in the case of the Oompa-Loompas, Dahl made his own edits, after being convinced of the need to do it by the NAACP. We don't know if Dahl would have been convinced of the need to make any of these new edits, because he died over 30 years ago. These unknown editors peddle their changes using his name, they trade on his popularity, rather than write their own unloved, status-quo compliant stories. We the public are so lucky that the publishers deign to keep selling his original books in addition to their Bowdlerised versions. But if they felt like it, thanks to copyright law, they could stop that at any time for the next 40 years or so. It's ludicrious!
