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?
But it’s not though. As I said in another comment, it’s like when movie directors keep releasing director’s cuts and ruining their own movie, or when comicbook artists retcon stories from way before with new coloring that looks like ass because “new audiences wouldn’t like the old stuff”.
For an author to try and grab the stuff they published, which is now out there and which people have read, and to try and rework that and change the whole of the prose, it’s a shitty cash grab that more often than not takes the old stuff from circulation.
It’s like when George Lucas did the whole special effects things in the original Star Wars trilogy and took the original versions from circulation, as if he was the sole arbiter of all things Star Wars and not like his work of art had entered pop culture - and, therefore, isn’t just his to keep tinkering.
An author’s work is very different from a filmmaker’s role. An author usually works alone - the creation belongs to them entirely. An author also usually holds sole copyright and can do as they wish.
