The whole thing. All of it. Is dumb.
Australia as a nation has its rules. Novak decided the rules didn't apply to him and looked for a loophole. "His team" found one and used the specter of the dollars associated with the tournament to try and exploit it.
A legal battle ensues and he wins, on the technical merits of how he used the loophole.
Then the country decides that there's a larger problem: politics. If you let him play fast and loose with the rules, then there are no rules. You can't enforce anything anymore. There's an election upcoming. They are at least trying to protect the public interest.
So they cancel his visa and expedite a court case to deport him.
End of story.
At any point, he could have simply left. But instead he decided to be a self important, entitled, prick. The rules didn't apply to him. His team made the mistake, not him. He was there for the love of sport. He was persecuted. He has views on the whole pandemic that he wants to share.
The country probably didn't handle it correctly from the start. But they did ultimately handle it in the way that enforced their rules. And they had to use their legal system to sort it out.
I'm not here to debate whether they were right, or wrong, just that they had rules and they upheld them.
But I have to say I'm glad that he lost. For once, a pompous asshole gets his comeuppance in spite of his money and relative power.
And it's led to some great memes and funny comments. So winning! On several fronts.
