I've actually been called a war profiteer by someone with no idea what they were talking about. Things play out pretty simlply to the person with no experience or stake in the military, or armed conflict.
To the simple mind, anyone working for the military in any capacity, is a "war profiteer", from the 18 yr old infantryman, to the lunch lady serving food on a base back in the US.
A video game manufacturer, or a movie studio, or X cultural enterprise depicting armed conflict does not have a stake in the creation or continuation of armed conflict profit, and as such, are not profiteers.
I tire of people who insist that media which deals in the depiction of conflict are somehow predetorial.
