Here is another angle to consider. How many of the viewers of Troy's 'free' plagiarized courses saw them and were impressed enough to convert to paying customers? Difficult to measure but Udemy will have a pretty good idea.

For Udemy to say that no money changed hands is a bit myopic, but perhaps this is unintentional. Money likely did change hands, but it was abstracted from the original transaction and only Udemy knows that figure.
