Yep, the reason the rules exist and are enforced is so you don’t have a brattish player ruining the game for everyone, which is exactly what happened here. I’m seriously side-eyeing Serena’s “women’s rights” comments because the person who had her big victory ruined and her record possibly tarnished was another POC woman, Naomi Osaka.
I find it (sadly) ironic that this whole debacle went down at Arthur Ashe Stadium. Arthur was the epitome of class on the court. You never saw Arthur engaging in McEnroe-like antics on the court such as breaking a racquet during a match because he was mad.
