people sometimes ask 'why GNU? Why free software?'
because it was only 29 years ago that people could be thrown in jail for most of their life for sharing the source code to the operating system they used, for what was basically an academic discussion of how it functioned. It would be another ~1-3 years before GNU/free versions of BSD(eg FreeBSD) were available/free and worked at all. That was what life in a proprietary world was like. That is what Microsoft would bring us back to.
