I wonder how they're counting ads that say "BS or MS in Compsci or Equivalent Experience" or something to that effect. I understand that this could deter some applicants, but I think that it's pretty clearly a go-ahead for applicants who don't have the degrees but think they could do the job (though presumably applicants with the relevant degrees would in aggregate fare better etc). I wonder this explicitly because last time I looked I did not see many mentions of degrees that weren't explicitly accompanied by the OR.
