I do not believe anyone would have any issues with creating forked/adapted/refreshed versions of literary works. We do it all the time. No one reads the original Grimm tales to kids because the original versions were gruesome. Many would count as horror. We tell kids adapted versions. But since they are public domain anyone can fork these works and create new versions. There is nothing wrong with updating works to reflect current cultural mores. We always did it and will continue to do it.
The issue is that this is done by copyright holders and the new approved version replaces the old version on the bookshelves because copyright gives them a monopoly on distribution. Unless you find it used, you will no longer be able to buy the old version. Some people want the old version because it is the version they know, it is the version they grew up with and it is the version they want to pass forward and because being a authored work (instead of folk) they want the version the author wrote with all of its cultural artifacts preserved.
To make the conflict clearer, imagine that once Windows 11 (or 8, or Vista) was launched, everyone on Windows 10 (or 7 or XP) would have been force upgraded to the new version and the old version would be deauthorized. Or imagine if copyright was infinite in duration and Disney bought the rights to the Grimm tales and now only the Disney versions are authorized for commercial distribution. You would simply not be able to buy the older version.
To me this makes it even clearer that the length of copyright being longer than the life of the author is an absurdity. Culture does not belong to anyone, it belongs to all of humanity.
