There is a weirdly racist trend where people blame hypothetical minorities when systems fail because management cuts corners. We saw it with the Boeing door collapse and now with the Crowdstrike crash.
There is no mythical "DEI engineer" doing sloppy work at these companies.
It's down to leadership cutting corners to make a buck. A software update causing a crash that takes down all of your customers is due to inadequate testing. It's not because some anonymous minority wrote the code.
