Whatever you think of Serena and Naomi (and I adore Naomi), there is no doubt in my mind that the chair acted improperly.
I think there was gender bias at work. The first coaching violation? Deserved. The second violation? Deserved.
But I cannot begin to count the number of times men have sat in their chairs on changeovers and had heated discussions with umpires, and nothing whatever happens. But when it is Serena, it is a game penalty in the final. Insane. Her words were actually civil -- saying she deserved an apology, no profanity, no threats.
Need more proof?
In this same tournament, we had a chair umpire come out of his chair to basically coach Kirios in front of God and everyone. The proper response would have been to enforce the code of conduct, but no. Ump goes easy on the man, and USTA backs up the umpire.
By that standard, Ramos should have come out of his chair and talked to Serena, calm her nerves, tell her he wants to help her. Nope -- game penalty (when the tirade was over and he could have let it go) to put Serena's opponent a game away from the championship.
Congratulations to Naomi, but what happened today was rooted in disparate treatment and sexism.
