I can't defend this kind of behavior, and indeed I've been very critical of the game industry and how closely it holds onto it's figures, while at the same time making claims about how justified the prices consumers are forced to pay (as well as things like paid DLC) without anyone being able to verify what they say.
The curtain over game finances is one of the big reasons why I am constantly pointing fingers at the industry for being greedy, and gouging us, and asking uncomfortable questions about how much these guys are taking home, in comparison to what they claim. Do game coders driver Ferraris, live normally, or eke out the popularized "hand to mouth" existance that is occasionally used to guilt us into supporting things like DRM, or whatever latest cash gouging scam has seen the light of day. We can argue this back and forth, and people can referance workers in the industry that they have met, but in the end nobody is going to know anything unless those numbers are made public, and the very fact that the industry is trying to keep them under wraps tends to make one believe that there would be some consumer backlash if people knew what the paper trail actually looked like.
I've been a big proponent of consumer advocacy for gamers for a log time, sadly getting something like that organized and/or getting existing groups to take us under their wing is not easy. With no direct pressure on the gaming industry from consumers, they really have no incentive to let their dirty laundry be aired.
