That's not necessarily true. In Central Europe, nationalism is alive and well (actually increasing due to the perceived cultural threat from the EU), and a picture with three different skin colors for three people will not be interpreted as affirmative action, but unwanted external cultural influence.
Particularly the black guy, as you don't expect to see black people every day.
In Hungary, at least, the original picture would cause outrage from the far-right and a measurable decrease in sales.
So, you're saying the Polish are racists and MS is just bowing to market forces?
