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?
If it’s the original author then I’m fine with it because they can do what they want with their art.
I hate it when companies that own the rights change the authors writing after they’re dead/incapacitated. Bowdlerizing an authors work to pander to markets or the superficial whims of “modern sensibilities” is grotesque.
