Earlier quoted context omitted.
That's definitely not the requirement! The requirement is to avoid doing certain kinds of "research" that the government disagrees is valid research to fund, characterized by the principles underlying it. They may have started by using certain keywords to find examples of such grants to terminate, but the requirement itself has nothing to do with words and everything to do with the intentions.
I know someone whose grant was cancelled for studying genetic diversity in animal populations.
Also, frankly, I heard a bunch of such stories and very often the grantees were misrepresenting their work. It actually did have DEI content in it and they were pretending it didn't. You can see how many people in this thread are arguing that all you have to do to comply with the requirements are use a thesaurus or misrepresent their work and then continue anyway. For as long as academics insist on total warfare and malicious compliance, expect universities to be blowtorched.
