Note to entrepreneurs hoping to build a business using illicit content: don’t grant extensive interviews (complete with pictures) to the Wall Street Journal. That’s what a pair of aspiring hackers did back in April when they described how their service, YouTVPC, allowed users to watch streaming TV shows and movies without charge.
