What is outrage culture about this is the framing as if it is a new phenomenon. Outrage sells.
Censorship in literature exists well before the current era (
A Clockwork Orange, for example). Book burnings, book banning, moral crusades are nothing new. If this pisses you off, then you should have been pissed off a long time ago. If nothing else, just be glad that this type of stuff usually backfires and just amplifies the work.
The beauty of the internet is that those original versions are available to you at any time. Once his work goes into the public domain in 2060, anyone can republish as they see fit. That includes the original works. If an author doesn't want their work modified or editorialized in any way, they should note that and put it in a trust.
