I disagree; actual incidents aren't hard to find if you read gaming-related media, both in terms of game-focused websites and developer blogs.
When I was around 12 years old, I sat down with some of my family members to play Dungeons & Dragons for the first time. I expected something involving benevolent wizards, chivalrous knights, and sly thieves meeting in a tavern to go on an adventure, likely involving a dungeon and a dragon...

I don't think those are proof of anything. The original creator of Dark Sun hypothetizes that WotC wouldn't touch the setting for X, Y and Z reasons, but doesn't know, and WotC wouldn't say. (Compare to all the people who say Movie X "could never be made today," ignoring how many movies of that type are still being made.)
A website got some letters from an unknown number of people and said "people are made we didn't mention that there's slavery in the setting" could mean they got three angry letters. We have no idea how widespread the response was, nor how seriously to take them. (A website getting brigaded by angry partisans is not representative of anything, as countless movie review sites being brigaded amply illustrates.)
And Paizo deciding to not do content that includes slavery means that Paizo decided not to do content that includes slavery, not anything significant about the market as a whole.
Honestly, Radiant Citadel is a great rebuttal to all of this stuff. It is openly and enthusiastically an incredibly progressive, utopian setting that includes plenty of real world ills, with multiple of its adventures addressing the consequences of colonialism. WotC isn't scared to publish this stuff, as we've seen as recently as
July.
After years of everyone trying to find Planescape and Spelljammer under every tea leaf, it's weird as hell to watch many of the same people try to conjure up a reason that Dark Sun hasn't happened yet, ignoring the very obvious reason that every time WotC has come up with psionics rules, a substantial number of Dark Sun fans are loudly furious that the rules aren't the same as they were in 2E.
WotC
clearly wants to do this. They would not have kept screwing around with psionics rules -- publishing them in a book as recently as November 2020 -- if they didn't.
