That's right, I think (and you seem to be agree) using another name than Baldur's Gate "3" wouldn't have changed a thing for them.
That's the exact reason why many people think Larian spit on them (and why discussions are so hard and emotional)
They have the rights, WoTC blabla, I know those things of course.
We don't know what their marketing research told them, so we cannot say if it would or would not have changed anything for them. It is certainly possible that using BG3 is a marketing tactic (not a "cash grab" as some others have said), and that's fine if so. It's a business too.
You're disappointed the game isn't going to be the way you envisioned. I get it and I'm not unsympathetic. But, that doesn't mean it won't come. And I am sure the name doesn't mean as much to the other side either. If Larian was making a game to suite the BG1&2 devotees, but called it something other than BG "3", I doubt there would be much discussion on the matter.
I think you're right again with the last sentences. They won't be such discussions if "the waited game" wasn't named Baldur's Gate 3... Except many wouldn't understand why it's not named BG3.
BG3 is a legendary name for those that waited for it. They were many illusions during this time, many "spiritual sons", many rumors... It's not something that was waited because of only nostalgia. Some BG3 forum on video games website were created in 2001 and have discussions (more or less due to circumstences) every years and this is the same for BG1 and BG2 forums before the EE comes out.
This name "BG3" is really something important for some players and everyone enjoyed to know it was really coming.
But what we see and what they say about it looks nearly nothing like a Baldur's Gate game... That's why I'm dissapointed. (please don't say I waited for a game of another ages etc... This is not the point, and this is not true).
