Probably the best example I can think of is Diane Duane reworking her Wizards series to make it modern-day, but there are others, including owners of a literary estate altering books left to them to make them compatible with current standards.
What do you think? Does it matter if it’s the original author or an inheritor?
YES, let’s rewrite all literature and make sure every character cast is multinational and multicultural. Remove all racism, sexism, bigotry and classism. Eliminate any and all text that is negative or potentially offensive. Get rid of difficult challenges and also make sure nobody gets hurt or dies in any story. No mentions of war or oppression and all romance narratives end happily for all characters involved or witnessing romance. Remove references to illness and also make sure all settings include natural environments that swath the characters in comfort and ease. No mentions of work or capitalism, absolutely no reference to danger and also make sure all stories have a happy ending yet also open ended so that endless sequels can be made. /s
