In the past White Wolf had a couple of imprints, one was:
The title that reminds me the most of this brand was: HoL (Human occupied Landfill), but there are more notorious books under that imprint. But White Wolf was already pretty niche, dark and horrific, especially when their most popular IP was Vampire: The Masquarade. Still they found it necessary to create a separate imprint for their mature/adult themes. I suspect that even the names White Wolf and Black Dog would be big no-no's these days. And the amount of trouble such adult themes would bring, would not be worth it to WotC (at this time). Getting trusted 3rd party publisher to do DS (and the like) I also do not see happening, as that feels like as them being endorsed by WotC and that would invite too much trouble again. Just opening up all the D&D settings might be disconnected enough from WotC to fly under the radar amidst tens of thousands of other digital products...
