My guess is that evolution in general has adapted on some level to dust from granite. It was around before land based animals. Just like it has adapted to trace quantities of other poisonous and harmful stuff.
Engineered stone might not be exact analogy granite dust, but different in way that prevent these mechanism to be effective.
the studies cited in other parts of this thread found granite dust to be more damaging to lungs, not less so
