If you watch the video you'll see that Markee produced it because of a mishap recently. After a "customer" made about $20,000 in purchases for virtual goods, they did a reversal essentially having that amount of money returned. Incidentally, there is a certain amount of time that a user can reverse purchases ( I don't believe a user can reverse a purchase that was made 3 years ago)---in this particular case, the amount it was stopped at was approximately $13,000.
In the end, notice that Markee's message is about stealing from companies that sell virtual goods and how the level of honesty in parents can directly affects their children's perspective on stealing. Although his company did take a large financial hit for the customer's reversals, it is more of an issue for his company to step up their legal strength.
Lesson learned--that goes to tell you that there are many dishonest and dishonourable people on the Internet and companies (in sales for virtual goods) need to take the necessary steps to establish a higher level of legal control.
