Right now, the display is "naked women in body paint", but with men it would be "naked people in body paint." The gender neutrality of the display would exist in more than just a semantic sense, but also in a deeper sense that gender wasn't considered a factor when they were making this display. Right now, that's not how it looks at all. It looks like they only wanted naked women to be associated with HyperMac's products. And the CEO's comments do absolutely nothing to dissuade that viewpoint.
Would people have still complained about objectification of women if there were men in the display too? Maybe. But they would have a much weaker case than they do now.
