They use it to claim people that are not white, cishet, able-bodied, male, etc. are hired for their "diversity quota", not their skills, while also appearing as reasonable to moderates. In my country (Hungary), similar backlashes were used to get minorities fired or not hired for some single minor mistake, and then hire a way worse non-minority. I was the victim of such thing, they asked my brother if I have "random violent meltdowns that end with destroyed equipment and bit co-workers", when my brother said no, they decided to make me write on a table (which I suck at), where I was "too slow", so they hired some more neurotypical guy, who had like almost zero programming knowledge, while I was described as "already having junior-level knowledge from open source projects".
