So I do think there is a more nuanced POV on this, somewhere in-between your point and @LuisCarlos17f
(and boy his arguments just make me disagree with him more).
Here is a piece of art for the Drow in Mordenkainen's Tome of Foes, released in 2018.

I don't love everything about the depiction of Drow in that book, and there is some I do not like, however I think it did make a solid effort at trying to make the Drow more nuanced than they have been in the past. Largely, that the Lolth-worshipping side of the culture is extremely toxic, made much worse by the insidious nature of the god they worship. But that other gods provide alternative avenues for the Drow, some good (Elistraee) and others more neutral. And of course, it addresses how the "bad drow" subsist on slavery, but that this doesn't define the entirety of their race, and that they don't rely on any specific race for forced labor.
At the time, I don't know how many people were offended by this depiction of slavery, or even this depiction of Drow. I think you can do something similar with that of Dark Sun, that yes slavery exists, but that it is in fact very very bad
. You can hire sensitivity consultants, and writers of various backgrounds, to help publish material that can address these real-world issues in a fantasy context without upsetting people.
Anyway, my point is that most people of various backgrounds don't like to just scrub fictional material of references to toxic material. What people do want is it written in a framework that takes in consideration various people viewpoints and backgrounds. Material written solely by a "white western male" voice has been the norm, and folks just want material provided by different voices. They don't want all negative associations removed; people know what is wrong and what is right.
