Black Isle didn't make BG. Bioware did. BIS, a division of interplay was the publisher. BIO was the developer.
Also, the game is called BG3. That comes with expectations. A lot of people bought and/or were interested in the game because it is literally a sequel in the series.
They did this because they know it would sell copies. If you think it's a coincedence that BG3 is gonna probably at least double the sales of DOS2, you are wrong. The combo of HBG-DND-Larian = lotsa sales.
Too many companies want the money from the fans of the original game they are remaking/continuing but don't seem to want to give them the stuff that they liked aboutt he game originally.
(This isn't bashing BG3 on its own; just a general observation of remakes/series continuation in modern times).
