I would actually suggest visiting the video even if you don't watch it since there's a list of primary sources in the description, a goodly number of which are archived:

https://archive.ph/8JAln -- WSJ (On the 2016 McKinsey study not meaning diversity pays out with increased profits)

https://archive.ph/8JAln -- Business Insider (Microsoft DEI firings; reiteration of commitment to diversity)

https://archive.ph/GPbiM -- Bloomberg (Zoom DEI department layoffs; reiteration of commitment to Diversity.)

https://archive.ph/HcfQR -- WaPo (Zoom and Snap cut DEI roles; "At Zoom, chief operating officer Aparna Bawa told employees that the company would replace its internal DEI team with DEI consultants who would “champion inclusion by embedding our values … directly into our people programs rather than as a separate initiative,” according to a Jan. 29 memo seen by The Post.")

The common thread here is that all of the departments are being dismantled, but the initiatives are being continued-- either organizationally or under different names. "We disbanded our DEI department" doesn't mean they're abandoning the ideology. The rock has been lifted and the bugs are seeking new cover. That is all.
