Can anyone explain why the sheetrock always cracks on vaulted ceilings? Why is it more prone to cracking than in the same room with a flat ceiling?

When that pole bends way down it places a lot of stress on them.
a few possibilities-
among them, more movement if trussed.
Longer framing members in a vault so more possibility for seasonal/heat/cool shrinkage being magnified.
Even with a ridge beam there'll be movement.
If not engineered properly, what's good enough structurally for a roof frame does not necessarily translate into fine for the sheetrock ceiling.
An engineer could draw the arrows of applied force and load that might make it more apparent.
