D&D without the rules and themes of alignment is just a generic fantasy adventure game. 5E was already an example of taking simplification too far and diluting the interesting part of the game. BG3 is making the problem even worse, but those without any experience with the rule system will obviously not understand the consequences of these decisions. The younger audience here comes from a videogame background, and that makes sense since that is the demographic being marketed to.
I'm sure BG3 will still be a good game, but this is one area where it's a major departure from authentic D&D mechanics (which are the reason for its longevity).
