I believe, but could certainly be corrected, that in the Airbus fly-by-wire system moving one joystick doesn't result in movement of the other so there's no feedback in that sense. Seems like I've read that the last joystick moved has precedence - it's imput goes to the computers unless the other joystick is then moved, which would result in that joystick having precedence. I also seem to remember that if both joysticks are being manuipulated opposite each other the left seat joystick has precedence.
Of course, in theory the limits built into the computers are supposed to protect the airplane from pilot input - you shouldn't be able to stall, roll, invert, overstress, overspeed, overbank, etc the plane. That's where it seems that the loss of data to the computers played a role - without data for a short time, the computers effectively said "We give up because we don't know what's happening" and all that built in protection went out the window.
