So there's a lot that's been said about the drow relating to this, and there's plenty of discussion that's been had and is still being had to this day, but to not derail into all that, one thing I will point out is that all the baggage comes from D&D itself, Larian didn't originate it. They're just running with the established lore of the setting they were given. I'll knock Larian on plenty of things, but I don't think this is a fair one to lay at their feat.
I think Larian stated at some point (or was it their ceo?) that they were given a lot of freedom when it came to d&d. And well, they did rewrite the mind flayer lore, including a character like Omeluum who is unlike others of his kind. So I don't think they were really that tied into writing Minthara as evil.
