Yeah honestly anyone familiar with marketing and communications departments (and especially those in higher-ed) is used to this sort of chicanery.
This particular instance is somewhat notable in just how egregious it is, but they pick-and-choose students based solely on ethnicity for photoshoots all the time.
Hey, at least they used pictures from actual students. I remember looking at promotional material from the higher-ed place I attended and I think I spotted one picture of a familiar classroom with someone I knew, with all the other pictures being of total strangers in rooms that I had never seen. As the school was rather small, I was surprised that it was the case, until I suspected the communication department, unsatisfied with what pictures they had, reached for stock photos.
I think if they did that, it would be a lot less of an issue. Here they took a genuine photo and made it fake. It's not representative at all, and it stinks of tokenism which I hate.
