You and I disagree on this and I'm 100% with Larian and Pathfinder on this issue. WotC tried to eliminate alignment in 4th ed and it was one of the (many) reasons fans rejected it in favor of Pathfinder . . .
Alignment is indeed a crucial part of the identity both of DnD and of BG. Then entire premise of BG was "can you resist the evil inside"? (the very real, ontological evil that was attached to your soul at birth; this premise was stolen from Ravenloft which is a setting that just doesn't work without 'real' evil).
And the BG3 story would suffer without alignment. We don't know how but we do know that Shar is going to play a major role the plot.. Shar gave birth to all evil, she wants to see all life snuffed out. And thus Shadowheart's dilemma . . .
Priests become rather bland without alignment. Make Shar the holder of the portfolio of darkness and deception and she becomes bland.
People just like alignment. Witness the thousands of alignment grid memes. In this WotC is simply screwing up and opening themselves up for a challenge from an alternative ruleset.
