Piracy is a hot button issue in the industry, with various agencies suggesting the upward trend in game piracy is responsible for billions of dollars in lost revenue. Small developers have been swindled out of their hard earned pay, and it has been used as a means to justify eggregiously overzealous bills like the Stop Online Piracy Act and Protect Intellectual Property Act.
Yet, pirates aren't all amoral scoundrels like so many would have you believe. A lot of people find their way to the high seas through relatively honest means because publishers have failed them in some capacity. Does it justify breaking the law? I'll let you decide.
