I know that's what those are supposed to mean, but that's not how the average poster on social media seems to use it.
Like with my example of the SpaceX landing failure, it was a booster that had flown over 20 times, had flown a trajectory at the edge of its performance, the leading theory (IIRC) was/is that some components on the legs finally wore out too much. Testing these limits has been one of the side-benefits of Starlink launches on used boosters.
So, seeing a bunch of people stupidly freaking out about this being due to DEI just shows that they don't actually know what "DEI hiring" is as a complaint.
