He knows the rules and when he saw blatant, not "imperceptible", as Mr Chiu writes, hand signals from Ms Williams' coach, he was within his rights to give her a formal warning.
'He said he made a motion, I don't understand what he was talking about, ' Ms Williams told Ms Wilkinson. "It was never a financially motivated decision nor were we ever swayed either way by any national federation".
The 20-year-old melted hearts when she burst into sobs as boos rang out following her emphatic 6-2, 6-4 thrashing of Williams in a controversial NY final a little over a week ago.
Osaka, the daughter of a Haitian father and Japanese mother who was raised in the United States, apologised to Williams for dashing her hopes of a record-equalling 24th Grand Slam singles crown before nearly dropping the trophy.
Tennis icon Billie Jean King said she believes tennis applies a double standard to women compared with men, and that a similar outburst by a male player would have drawn no repercussions.
Trailing in the second set, Williams received a game penalty for the verbal altercation at a change of ends where she called Ramos a "thief", after previous code violations for receiving coaching from the stands and smashing her racquet.
Osaka also admitted that she had no idea what was truly happening between Serena and the umpire, because she was taught to turn her back and stay focused when competitors confront the officials.
The 20-time Grand Slam victor was deducted a game and a point for three violations.

"I don't think I even thought about feeling sad because there's no experience for me to draw on in any other Grand Slam final", she added.
Standing on the podium waiting to be handed her trophy and a winner's check for $3.8 million, Osaka heard only boos as an angry crowd took out their frustration on Ramos, who stood to the side. No Serena, you are obfuscating the whole issue and, sadly, a lot of people are falling for it.
