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?
I think if you go to all the effort of writing, editing, publishing, and distributing a book, you should make sure it’s what you want the world to read. Rewriting your book after the fact is either lazy or pandering in my view.
