The fact is that this was widely considered offensive and unnecessary, and the CEOs response only made it worse. No one has the right not to be offended, but everyone has the right to speak out and not buy a product for whatever reasons they choose, which is exactly what happened.
Personally, I don't have a problem with naked people in body paint as part of a display; it does everything you want a display to do, it catches eyes and it sticks in memory.
But why did they only choose naked women? There are no painted male models in their staff photo from the event.[1] Was it decided that including naked men would somehow hurt the effectiveness of the display, and if so, why? Certainly there were willing male models, so it seems that HyperMac just steered clear of hiring men. The accusations of sexism (or more accurately, objectification) all springs from that, and the unwillingness of the CEO to even acknowledge that as a concern is honestly disturbing.
