Also DEI officers are a thing only at companies large enough to have an HR department. Their entire purpose is to ensure that the company doesn't get sued or fined for making illegal race-based hiring decisions. Once all the big companies have filled that new title there's not much reason to expect lots of job postings for the title: the market is saturated. Even if no company eliminated their DEI officer position you'd still expect the number of job postings to drop! Hiring for new positions follows a sigmoid curve, not an exponential or even linear one.
