Why did Microsoft photoshop this ad?

Found the difference between the two ads? Yes, the black man in the middle was replaced by a white man. Why? The image on the top was used for USA marketing purposes. The one on the bottom was used for Poland. Microsoft has updated the image on the Polish site and release a statement on Twitter saying:

Marketing site photo mistake - sincere apologies - we're in the process of taking down the image http://bit.ly/2B0Yk ^LG
