Assuming I’m okay with removing the racist and sexist stuff, I don’t really have a problem with them removing the fat stuff, as Dahl seems to almost always depict it as villainous and/or gross.
The main issue I have is the quality of the replacements. The Telegraph citation purports to lists all of the changes. Sometimes they seem to care to the lyricalness of Dahl’s work, but sometimes it’s entirely lifeless. Sometimes they try to keep as much of the original text as possible, and other times it’s just entirely functional.
As for the general concept, I’m generally okay with it as long as they’re open about it and the original is still available and clearly the original. Dahl himself changed things in his books for this reason. It’s not, however, clear to me that this is being followed, as these seem to be describes as new printings, not new editions, and there doesn’t seem to be any reference to the fact that the text has changed.
I do like the updated Rhymes for Sponge and Spiker, though. Not because they get rid of calling them fat and slim, respectively, but because they’re longer and actually in the Dahlian style:
Before (2001 edition):
Aunt Sponge was terrifically fat,/And tremendously flabby at that./Her tummy and waist/Were as soggy as paste -/It was worse on the place where she sat!
After (2022 edition):
Aunt Sponge was a nasty old brute,/And deserved to be squashed by the fruit!/We all felt a big bump/When we dropped with a thump./We left Aunt Sponge behind us/But you needn’t remind us /That we shouldn’t feel rotten,/For we haven’t forgotten/How spiteful she could be!
Before:
Aunt Spiker was thin as a wire,/And dry as a bone, only drier./She was so long and thin/If you carried her in/You could use her for poking the fire!
After:
Aunt Spiker was much the same/And deserves half of the blame./Ta-ra, Aunt Spiker!/(Though we never did like her)/It’s sad but true./If only she knew,/How the absence of charm/Can do so much harm./With thoughts so frightful/One can’t be delightful/And now worms will have Spiker for tea!
