They probably wrote it because Coinbase stood up to BLM activists internally and the NYT is the media arm of BLM. But you get these accusations constantly against companies. "I felt ignored in meetings therefore the firm is sexist and racist". No, that happens to people all the time, including white men. A better explanation is maybe you weren't saying anything worth listening to in meetings, or you feel you were but your manager disagreed.

when most of your black employees leave because of what they feel is racism in the workplace that’s harder to ignore

They weren't ignoring it. Some of these people weren't even saying they felt that way to Coinbase - one of the people who claims she was bullied also claims nobody told her how to make an official complaint and that's why Coinbase have no record of her views. Complaining to HR has to be the easiest task in any modern corporation; if she couldn't figure out how to do even that then we probably found the explanation for why she felt unappreciated: maybe she just sucked. Or maybe she's made up this supposed racism after she left, as part of achieving other ends (like getting in the NYT).
