International Law

It's definitely a much better strategy than annoying plenty of users (even legit ones) or threatening to sue or anything. And, I have no doubt that it's probably even effective on the margins among a few folks who appreciate being treated at least somewhat as a human, rather than a criminal. But, the company is still going to face this issue long term, and it seems like a better solution is to figure out business models that don't view such sharing as piracy, but a way to further extend a business.
