What I'm missing is 'cause'. The article doesn't appear to say, or I missed it. What I don't see is Google's 'standing' in all this.
It's well known that you can sue anyone for anything in the US - but that's not quite how it works. In order to sue someone, you have to show 'cause'. That is, you have to show that you were harmed in some fashion.
How did these malware people directly harm Google? What is Google's cause? How do they have standing to sue these people in a civil court?
In simple terms, I can't really sue you if you punched someone else in the mouth. You didn't harm me. The person you punched in the mouth can sue you, they have standing - that is you harmed them.
I am way too lazy to go wading through thousands of pages of documentation for the case. Well, that and I lack the time and expertise. LOL
