1) it sounds crazy because it's actual statistical malpractice. See the many other comments explaining how it's bullshit

2) the significantly backlash is interesting, primarily because it centers around the bullshit statistics that companies pat themselves with. The hiring process is so nebulous and unknowable to the potential hiree that no person can really know whether they were denied a job due to dei policies. Yet we simultaneously assume that all non white people hired are being _hired because_ DEI, which really just undervalues the nonwhite population, as if they truly deserved none of the jobs, wouldn't have gotten any without the help. This combined into the rage that certain people feel about what really appears to be a back pat circle around naming a git branch and changing security terminology.
