So were you against Wizards removing the harmful Romani stereotypes from Curse of Strahd? Was that bad or good to you?
I am going to have to admit to not knowing exactly what happened with Ravenloft. I ran it using the initial 5E version and ran the Vistani as fully developed three dimensional characters. I ran the game from the perspective of everything that's happened in Ravenloft is sort of on a repeating loop with the same things happening over and over again. By virtue of the Vistani being able to leave Ravenloft, my group eventually found that they were the only group that had full agency.
Now I understand that they did a revised version, but I was done with my game by then, so I never looked at it. From what I understand that was the "revised" version. From looking at Amazon, you can still get both versions, so I don't have any problem with that. If they stopped selling the earlier version, I think it would be a similar situation to what is being requested here. I wouldn't support that. But I also don't expect anyone to care about my opinion since that's something which has already happened years ago.
Now there's no reason that every version of every game has to stay in print, but with PDFs (and you can get the original AD&D module which I've also played) I don't see why there's a need to make anything disappear.
I am anti censorship to the core, so I'm in favor of more speech and discussion, even when I don't like it. And yes, I can say that a company voluntarily removing a product isn't precisely the same thing, but I'd rather have something like
James and the Giant Peach with the original text. And all of the edited versions of movies that have the naughty bits taken out, well I feel the same way, even if naughty bits aren't the reason I watch something.
I do think that this really means that WotC has no real interest in the Mystara property, otherwise they would already have made the changes to this product in the same way they did with Strahd.
