Sexualizing violence is always gross; the fact that it's being done by a company that has shown a deft hand when it comes to objectifying and alienating women, and the fact that it's being put out for a community that is far from friendly towards women, makes me more than confident that this is an expression of the obvious misogyny that video game manufacturers pander to all the time. It's less that the statue itself is pure, distilled hatred of women, and far more that it taps into and represents really fucked up views of women and sexuality and violence that pervade this community.
Things don't happen in a vacuum. For example, woman gets blown up in Zero Dark Thirty. If they had offered a mutilated torso with giant bouncy tits in their collector's edition, it would just be baffling. But because political thrillers rarely trade in the sexualization of violence and the marginalization of women into walking, occasionally talking tits and asses, I would consider it just a weird concept and not an expression of misogyny. But because the products in our industry, especially the more violent games, have an undeniably history of marginalizing women and making light of violence towards them, in addition to generally highlighting their tits over just about everything else, this comes off as a natural expression of that shitty, shitty attitude.
I'm reminded of those racist pick-a-ninny dolls from the South during the 1900's. Was the doll itself inherently racist? No, probably not, some black people did look like that. But the attitudes and concepts and desires behind the creation of those dolls were absolutely racist and contemptuous and vile, and that means that the product created to satiate and exploit those desires was racist too. It's the exact same situation here; a statue of a woman's violently ripped-apart torso is not INHERENTLY, ESSENTIALLY, WITHOUT POSSIBLE EXCEPTION sexist, but it's undeniably playing into some ideas about women and violence and sex and agency that are fucked up and disgusting - and as someone who hates how prevalent those ideas are in my community and in videogames at large, I'm going to criticize both the existential attitudes themselves AS WELL AS their blatant manifestations.
tl;dr if someone could not exist without seriously fucked up views on women and violence, then it is by definition an expression of those shitty views, and that makes it sexist and misogynistic. A product that capitalizes on a violent fascination with the sexualized destruction of female bodies (except the tits, because those are the parts that matter, amiright!) is as gross as the attitudes that fostered its creation.
