Agree, never gonna happen. They have positioned themselves in a way that they can not remove themselves from. Anything even remotely "risky" in the slightest way is a no go for them. Taking creative chances of any kind is off the table for wotc, for the very long foreseeable future.
I think a lot of people will will (and have!) take exception to the idea that making content with a diverse and inclusive audience in mind is (a) inherently less creative, or (b) even remotely risky. In both cases I would argue that it's exactly the opposite, though for the first I don't have to as
@Irlo already put it better than I ever could:
Sometimes — maybe even oftentimes — writers and publishers fall back on tropes and “evocative” language common to the genre without much if any reflection. Making some effort to dig into those choices and to hear other perspectives about them and to be a little self-critical can show that what we intend to evoke is not in actuality what we do evoke through our writing. That’s when it’s more creative and more challenging to change it. Let’s say what we mean to say, without dragging all the unspoken, unexamined, and sometimes hurtful baggage into the game.
In the second case, well, let's think about. You've said that the audience who are actually upset with terms like "savage" or "dim-witted" is pretty small. I'd be willing to grant that (though I will say that objections to other things like slavery and madness have been long-standing and widespread). Think, then, about the sort of people who would object to those changes. There's a whole, -cough-
RPG Site and forum full of folks who would throw around terms like "wokescolds" in reaction to changes like these. If, as has been asserted, there are more people who hate these changes than have been demanding them (as opposed to those who who are fine with, or appreciate them; something I'm not willing to dismiss by the way!), then how is actually going through those changes, presumably just because they think it's the right thing to do,
not risky? On the other hand, how is writing the same old problematic tropes that appeal to the same old audiences that have always been catered to in the past... how is
that riskier? How is it risky at all?
