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?
Don’t sound too patronizing now.
Also, it’s a work of art, it’s not a car or personal property. It’s like when George Lucas thought it fitting to change everything up in the prequels, then remove the older versions from circulations. It’s presumptuous of the author to think they hold the sole truth about something just because they wrote it years ago, and modernizing the prose is just a cash grab.
