IMHO responsibility lies with the moving aircraft. Someone in the cockpit needs to have their head up (no, not there!) and looking around. If the Comair wasn't parked yet - why didn't someone in the A380 notice it was sticking out more than the parked craft? They can't see their wing tips - but they can see what is ahead of them on the flight line.
A pilot who is not constantly and vigilantly aware that the "World's biggest passenger plane" is going to have more clearance problems than the average plane (up to 30 feet per side more than a 747) - probably should not be crewing the "World's biggest passenger plane."
I notice ATC had to remind the AF crew to shut down their engines so the emergency trucks could move in - but I cut them some slack on that - they were no doubt a bit shaken emotionally after the collision.
