It's important to keep in mind that FaceBook is an enterprise founded by an individual who appears to have many of the traits of sociopathy, and that an overwhelming amount of shady, anti-privacy, socially-destructive, and downright exploitative behavior has been credibly attributed to them over the years. The second sentence of TFA claims that the HUD's opinion of FaceBook is that the company "...enables and encourages discrimination based on things like race and religion, as well as sex, by restricting who can see housing-related ads on its platforms and across the Internet." This should come as no surprise from a company with the kind of track record that FaceBook has; the company's founding purpose was, after all, to judge people based on superficial traits.
Rot of this kind, when located in the head of an organization or creature, does not go away easily. It has been obvious for some time now that the culture in the leadership echelons of FaceBook is deeply amoral and disinterested in societal health. Although it's a very touchy subject (especially around tech sites), I think there's a strong justification to start really questioning whether or not a person who is interested in the health of society can continue working for FaceBook.
