Actually, that's Gebru's point. Gebru was pointing out frustration that LeCun was focusing on this narrow question of statistical bias, rather than the broader social issues you're getting at.
Your comment, among the sea of others, got through and made some sense to me. My follow-up questions are:
Does that negate the truthfulness of LeCun's response?
What would Gebru rather he do or say?
I feel like I can't tell what the desired form of action is from the article, and I'm unsure what good it does for removing bias from ML to attack prominent figures (on twitter let alone anywhere public).
