I would wholeheartedly agree with the D&D people if something was taken away from them, but it clearly is not. All that BG3 does over BG2 is to make it BETTER an experience, offer more options, offer more player agency and make it a more cinematic experience.
Not even a hardcore BG fan, but comparing BG2, the Baldur's Gate everyone thinks about when they think Baldur's Gate, one of the best RPGs ever made and a game that set the foundations for all CRPGs onwards, to the glorified demo of a Dragon Age-esque game, and saying the latter provides a better Baldur's Gate experience, is just plain silly.
