I think we all agree on that point, the data part in itself has its uses and is fine, mostly.
But the "fickled crowd" problem is how much time and effort Larian is taking to fine-tune something in the hope it will please absolutely everyone, from the data but also from all the noise in their forums, instead of assuming their identity and having a clear vision of what they want. They have a fine record after all, and BG3 is great as it is.
Not only those changes can only tend towards a "neutral" result, which isn't necessarily good quality. But it's also a risk for the project itself. From the reactions above, it's interesting to note that people don't like to be reminded of that and prefer to think Larian is cool because they linger as they please. Another game does that, something to do about stars
It's just how they
show, I like to hope they're not fools and won't fall into that trap.
