Did you read the rest of the article? It talks about how she talked with others in the company about this, someone above her took it very personally as suggesting he was racist, and her prompt firing. It also highlights how bungie was exposed for both racial and gender bias by reporting just a few months before she was hired, indicating that these exposed problems likely still existed.
I don’t mean any harm when I say this, but why would you jump to the defense of a company in the first place, dismissing claims of racism or other forms of bigotry? The world is incredibly biased, and regular large-scale studies on company culture (and social culture) reveal widespread bigotry in our world. Simply assuming the status quo absent enough evidence on either side to clearly paint a picture is more often than not correct. What purpose does trying to discredit her accomplish here? How do you think it makes black people feel to see the only reply in a thread is an attempt at discrediting her?
