Mad Max also has positive messages. Just because it isn’t a happy setting doesn’t mean the things it has to say aren’t good things to be saying.
Yeah, the bad things in DS have very clear, massive signs hanging over them that read "EVIL" in big, bold, flaming letters.
There's slavery, but it's based on power and it clearly doesn't work. There's those with privilege, but they're all very evil, usually getting their power directly from even more evil creatures who are blatant authoritarians. There's xenophobia, but it's everywhere and not associated with one culture or race. There's unchecked environmental abuse, and everybody knows it's seriously messed things up and it can't be fixed.
IMO, the most "problematic" parts of AD&D Dark Sun are: the depiction of Elves (a whole race that has antisocial personality disorder), and the depiction of Muls (sometimes described as degenerate half-breeds, IIRC), and both of those could pretty easily be modified and cleaned up.
You can just make the chances by rebooting the setting. Simply ignore the Prism Pentad stuff. Poof, it doesn't matter any more.
Yes, but then people will assume that the characters they know still exist in and around Tyr and that the plotline is still going to happen. You have to say something about what happened. Even if it's, "nobody in the Prism Pentad books ever returned to Tyr... not Borys, not Rajaat, not Rikus, not Sadira, not Tithian... no trace of Ur Draxa was ever found".
If you want to just handwave it away you certainly can, but the campaign setting book needs to satisfy the people who will read that and say, "No, that's dumb there was already a story."
