The problem is obvious from the picture
Looking closely at the picture, it's clear that there are no cupholders. So, clearly the pilots need to balance their cups on some handy piece of the control panel when they need their hands free for grabbing the controls/stewardesses/etc.
So, all Airbus need to do to remediate the problem is to install some cupholders. I'll bet that in Boeing cockpits, being made in America, there are about 20 of them.
