Is it not responding to consumer demand?
Are you suggesting that as soon as something is published, the author looses control over it, is no longer able to edit or amend without some form of reactionary committee censoring their work.
A few years ago the Pogues were fully behind the de-faggoted Fairytale of New York version. Should they have been censored, their speech restricted, made to keep singing lyrics they no longer wanted to. Would you send language police to their gigs?
Artists, authors, and publishers choosing to move with the times is not censorship. Mandating what artists, authors and publishers say or write is.
Wow - so much inferred from three words and a hyperlink!
Might I point out to you that Roald Dahl has been dead for quite a long time now and so is unable to give his consent, and if he were still alive I stongly suspect his response to a request to change his work in the manner it has been would be quite short, and encompass both sex and travel? Shane MacGowan is, on the other hand, still alive and can and should make his own decisions on whether or not to change the lyrics of "Fairy Tale".
As for consumer demand, I'd be interested to see any actual evidence for that consumers were wanting them re-written - the cynic in me wonders if there's a warehouse full of the original versions somewhere that the publishers want to shift, and reckon a bit of controversy will do the trick...
To treat your words in the same manner as you treated mine, are you suggesting that the original versions of Dahl's works in every library should be replaced with these new versions, and perhaps the originals burned so no-one has to suffer the potential injury of reading them?
