it's easy to deduce that's a manufacturing type of issue, either from the molding, or the machine that grabs the hands and crams them into the torso arms on the assembly line
if it bothers you, I suggest you request replacements from Lego's customer service request form. let them know they can't get away with it. they won't know it's a problem unless customers complain about it. after wasting lots of dollars sending out replacement torsos, they might spend some money fixing the problem in the first place
(be ready, they will certainly ask you for pictures to call your bluff for asking for so many rare torso replacements)
