On the other hand the linked article doesn’t really add any new information on top of that quote.
Maybe the best part of the linked article is the discussion at the bottom where people are accusing Eurovision of fraud an speculating on where the votes would have gone.
Neither article lets you know how a national jury can give tampered results. I thought the jury was chosen by the nation so if the nation has an agenda (like say, voting for Russia friendly countries or for Ukraine) I would expect a jury to be assembled in that way
As to the tampering: from other sources I understand the juries colluded to help each other through their semifinal (https://wiwibloggs.com/2022/05/15/flemish-broadcaster-vrt-cl...)
That page also hints at how the collusion was detected: by looking at the degree of similarity between the votes of each country’s individual jury members.
From the list you can take pairs, and check it again the jury voting results:
Azerbaijan
Georgia
Montenegro
San Marino
Poland
Romania
