Hasbro wants to turn DnD into an expanded, watered down, commercial universe. And they see the “sweaty nerds” that built the franchise as impediments to that goal.
They don’t care about current fans. They want the mass market watchers that turned out in droves for Game of Thrones and its “European history copy-paste but with dragons”.
Nevermind the fact that DnD built on the framework laid by writers like Tolkien to create what was essentially the lexicon for modern fantasy, and is essentially the bedrock for almost every western fantasy creation since the 1980s.
