And yeah, I also very strongly agree that a huge part of Swen's decision to pivot away from not just BG but D&D entirely is because his interractions with WotC and Hasbro proved to be unpleasant and left him with a bad taste. Any developer that works with WotC walks away having hated their experience. That's WotC's record, especially in recent years.
I doubt Larian moving away from D&D is some kind of WotC boycott. I mean it might controbute it, but I would be surprised if Larian stuck with D&D.
They are a studio with their own style, ideas and identity. They created their take on D&D game, and the most prestigious PC IP at that. Sure, a business focused CEO might double down on BG3 success to milk it for as much as it is worth, but Larian is a private company - and Sven is clearly passionate about creating games. They did BG3, brought a lot of eyes on them, made money and expanded the audience: now is time to invest and try something new.
While milking established franchises is how gaming industry functions, it is not healthy way of doing it. They would only be point to making Baldur's Gate4, if Larian wasn't able to pull of what they set out to do in BG3.
