We know that Alysa Butler felt unappreciated. I'm hesitant to believe the NYT is even representing her opinions fairly. If you read what they've written about carefully, the article doesn't have her accusing Coinbase of any sort of racism, the NYT is just weaving her experience into a story that they construct elsewhere (normal practice in newspapers). A 'diversity problem' is different from racism. 25 year olds being ignored in meetings is not a new phenomenon either in my experience.
