I don't think there would be any negative consequence to changing the name of the game. Nobody cares for it to be called BG3 - not the DOS fans, and not the fans of Baldur's Gate. All that titling has done is make fans of Baldur's Gate angry. The DOS fans couldn't care less what it's called. So, they should change it.
And your relating to terrorists the people rightfully upset about Larian's false marketing and cash-grab move calling their D&D game "BG3" is deplorable. It also is astonishingly oblivious in that it misses the point that if the name was changed there'd be nothing to embolden Baldur's Gate fans concerning, since they could no longer criticize Larian's D&D DOS formula game for not being like the original PC series Baldur's Gate. I don't know how your logic works, but if the name is changed then the critics of Larian's game being falsely named and disrespectfully co-opting the Baldur's Gate series won't have anything to criticize anymore.
Its not false marketing.
They have a game set in Forgotten Realms Faerun Sword Coast with authentic D&D rules. They are telling a Forgotten Realms Story connected with Baldurs Gate and D&D mechanics sanctioned by WOTC. They wanted to get BG IP for years and were enthusiastic about it. They are one of the defining companies of the genre today that once BG was in.
I am playing P&P for 30 years and everyone in my group loved BG. I am way more excited by a FR story and mechanics than I have ever been for DOS I played those games but D&D is the real deal there's way more emotional grounding and roots and higher stakes.
Putting BG1-2+IWD on a pedestal with noone being allowed to touch them ever again does not help anybody.
Better use that Resurrect scroll than letting it rot.
