I have worked in the software industry for years, and one of our big concerns has always been piracy. We have spent a lot of money building technology to make it hard to pirate software, educating the public, and bringing pirates to justice. Software piracy losses around the world are enormous. I work at Microsoft, and they are a global force against software piracy.
But did you know that there is piracy outside of software, music, or movies? Even in the world of woodworking plans there is piracy. Steve in Marin, from Woodworking for Mere Mortals has written an excellent article on his website with an accompanying video.
