Williams, 36, was docked a point and then a full game after picking up three code violations for receiving coaching, smashing her racquet and then verbally abusing Ramos in her defeat by 20-year-old Osaka on Saturday.
The cartoon, which features Williams mid-tantrum while a faceless Naomi Osaka speaks to umpire Carlos Ramos as he utters the words "Can't you just let her win?", was featured in Melbourne-based newspaper the Herald Sun.
After the match, Williams accused Ramos of sexism, arguing male players have been more aggressive verbally with umpires but not penalized as she was.
The women's pro tour agreed. "We do not believe that this was done last night".
The US Open fined Williams $17,000 for her protestations, although she collected $1.85 million for finishing runner-up at Flushing Meadows. Williams took offense to the referee's accusation that she would cheat.
It all started when Ramos decided that Williams's coach, Patrick Mouratoglou, had advised her from the sidelines.

Mobile phones, the biggest USA import from China, have so far been spared, but would be engulfed if Trump activates the $US267 billion tariff list.
This resulted in another code violation and her opponent, Naomi Osaka, was awarded a game.
Billie Jean King, the former world number one who founded the WTA in the 1970s, said on Tuesday all sides shared blame for the incident, saying Williams was "out of line" but that Ramos could have prevented the controversy with more leniency and clearer communication. I'm really sad to lose the final in this tournament because I had too much passion playing the final, trying towin the title again. "This is not the hill you want to die on".
The tournament's main showcourt was given a new roof two years ago, but the lack of ventilation within the arena when the roof is open drew plenty of criticism, not least from the likes of Rafael Nadal, Roger Federer and men's champion Novak Djokovic.
"Serena got angry on the court", he said.
Though he agreed that "the chair umpire should not have pushed Serena to the limit, especially in a grand slam final". "Was, in my opinion, maybe unnecessary".
Asked how he deals with decisions that go against his team, Curry added: "It's tough but with experience you understand how you can control your emotions and how you can stay focused on what the task at hand is and that's just winning basketball games and not letting anything get in the way of that".
"She's right [Serena Williams] when she says the men say 10 times worse and don't even get a warning". "I think that's probably the context of the conversation". "I think the umpires, they antagonise a lot of players".
