I guess there wasn't a preponderance of bribes and Trump doesn't have a notable preference, so the grotesquely corrupt and incompetent Supreme Court has to turn to someone else to tell them what to do.
An amateur tip (at this point, apparently even an amateur understands the law better than the SC does) - look for precedents in similar instances.
For instance, are phone companies liable for what their customers do on their phone network? Are road construction companies liable for what people do on the roads? Are power companies liable for what people do with their electricity?
The answers are no, no and no.
So now ask yourself, why is that?
And if you're able to actually reason (somebody can maybe walk the slower and/or more corrupted justices through the steps), you'll find your answer.
Best of luck.
