3 History  In 1984, Richard Stallman of MIT, started the GNU project with the goal that no one would ever have to pay for software  The idea is that the source code is fundamental to the furthering of computer science and freely available source code is truly necessary for innovation to continue  GNU General Public License (GPL) was created to prevent businesses to co-opt the code for their own profitability
