There's a whole section of the article titled "DEI'ing inside" where they explain some tactics that fit the bill. Of course nobody said the phrase "DEI purge", that's the author summarizing it for a headline. I'm not really taking a stand on whether it's accurate or click/rage-bait, just saying this is standard writing style to summarize things into themes and it appears they have the content to back it up in the article, it shouldn't need to be a direct quote.

Because the rest of the items in the headline are labor related, the implication is that "DEI" is getting fired, whatever that means. People in this comment section who did not read TFA are commenting on "DEI" firings, even though there's nothing in TFA about that. It's a little worse than clickbait IMO.
