I agree entirely, and also agree that this game is not truly a Baldur's Gate game. I wouldn't go so far as to claim it is D:OS3, but it is more D:OS than it is BG. The "BG" in the game title is undeserved (thus far).
Minor quibble, but I'd say it's the "3" part that is currently undeserved. It's the "3" that implies it's a direct sequel to BG1&2 since those games were a ~continued story, but
currently BG3 seems to stand on it's own with only easter egg references to BG1&2.
If Larian had named the game "Baldur's Gate: [Insert Good Subtitle Here]" (similar to the tabletop module BG: Descent into Avernus), then there would be much less of a problem. The story does take place near and heavily involves Baldur's Gate after all.
