It's a lot of mental work to rally the emotion of revulsion over the evil they might be doing that is kept secret.
I was once fired, ghosted style, for merely being in the same meeting room as a racist corporate ass-clown muting the conference call to make Asian slights and monkey gesticulations. There was no lawsuit or payday because "how would I ever work again?" was the Hobson's choice between let it go and a moral crusade without a way to pay rent.
If instead I were upset that "not enough N are in tech," there isn't a specific incident or person to blame because it'd be a multifaceted situation.
