The article in question provides several examples of public figures making these points.

I've personally encountered people and organizations that . Several who, for instance, decried white flight on one hand but on the other hand criticized whites (and Asians) moving into poor neighborhoods in San Francisco. One company I worked at set up a system of reserving headcount specifically for underrepresented demographics, while simultaneously declared that any notion that the company extended preferential treatment to said groups was hateful and not acceptable.

I think these people are well-intentioned but are too scared to confront controversy or navigate nuance in their views. So they resort to this sort of contradiction to try and avoid it.
