Whatever you like TB or RTWP, it's done so it's not important to argue about what is Baldur's Gate 3... But it looks obvious to me that RTWP suits the philosophy and the feeling D&D players are supposed to experience, while TB suits more the way it's played for convenience.
How strange then, that WotC saw Divinities and said: "Yes, those are the guys who can do justice to our IP. Let's have them over an pitch BG3 to us". Maybe, just maybe: projecting your own preferences on the source material a bit much?
