People that complain about Smurf IN QP

Well, if I wasn't wrong, the definition of Smurf is: A alt acc created to play on elos that aren't the one that you belong.

And it's exactly that, why people complain about smurfing in QP??? The enemy belongs to the category QP Expert and he is on QP Beginner? I really can't understand these people, for me, they are exactly the same than the ones that only walk into a roadhog hook and blame their ball/doom/Winston for not being Frontline.
