No one is saying the new game is bad or shouldn't be made, but it is not "BG3" in spirit, it is only BG3 in name.
I don't really think the distinction is important unless you're a raging fanboy and raging fanboys can rarely be pleased, so since Larian just can't win you guys over it's only logical they shouldn't even try. I did like that story about childhood shower time, it was a pretty spot on allegory to you guys, hah.
