Name another Major final where anyone, male or female ever did something like this. Doing what she did at center Court of the US Open final is just crazy, and ruining the day for Osaka the 20 yr old champion. The $17,000 fine she got was not nearly enough.
You are wrong. It is an easy search, first of two descriptions below from a final, way more extreme and the penalty was a point vs a game. Link is to general verbal abuse not necessarily in majors or finals but certainly ample evidence that abuse by males is held to different standard.
"Five-time major champion Martina Hingis held a 6-4, 2-0 lead on legend Steffi Graf in the 1999 French Open final when she disputed a call and became angry when she thought the umpire checked the wrong mark. Hingis walked over to Graf’s side of the net, kept complaining and refused to play until talking to a tournament referee. That move backfired too – Hingis was assessed a point penalty – and the meltdown was on. Graf came back with ease, winning her 22nd and final Grand Slam title before retiring one month later. Hingis would never win another.
From the US Open (not final, but 4th round of same tourney):
"With all of New York on his side, the irascible, 39-year-old Connors was at another make-or-break moment in his storybook run at the 1991 Open. Trailing by a set, the birthday boy hit an overhead that was called out by the chair, bringing a set point for Aaron Krickstein that could have given the youngster a two set lead. Knowing he had the full support of the crowd, Connors set in on the chair umpire, delivering a bullying verbal beatdown intended to win points with an already-rabid crowd. Connors won the next three points to even the match, went off again on the umpire later in the match when his back was against the wall and, of course, beat Krickstein in a match that’s become a replay staple during U.S. Open rain delays for a quarter-century."
