Twenty years ago, even staunch proponents of free and open source software like Richard Stallman questioned the social imperative for free hardware designs. Academics had barely started to consider the concept; the number of papers coming out annually on the topic were less than could be counted on someone's fingers. Not anymore! Not only has the ethical authority of Stallman embraced free hardware and free hardware design, but so has the academic community. Consider the graph below, which shows the number of articles on open source hardware indexed by Google Scholar each year from 2000 to 2017. In the last 17 years, the concept of open source hardware has erupted in ivory towers throughout the world. Now more than 1,000 articles are written on the topic every year.
