So would we be having this dicussion if the author had written: "Two years later, all the “diverse people” they had carefully collected had left, and the company had backfilled with almost exclusively cisgender heterosexual white guys."?

My guess from your comments is: probably not, from your perspective? Much of your original post that I disagreed with is about the use of the term itself.

But I don't get that sense from the reactions posted by others, since those other quotes I included don't seem to be justified by this article at all, to me.
