I see this as a case that is often misunderstood/miscalled both ways. The dribblers sticks the arm out, but no contact. The crowd, in perfect unison:
"He's pushing off!" Or the defender is lunging to try a steal and is hopelessly out of position, but before he can commit the blocking foul, the dribbler reacts, changes direction, and sticks out a forearm shiver to ward off the attack.
