@jwildeboer @tante @till The GNU GPL v1, was published in 1989, before that we had the Emacs public license. In 1991, home PCs where not "readily available" (despite being a lucky hacker, getting a 386 was impossible -- which is where I ran and ported early GNU/Linux -- it did not have TCP/IP .. let alone Ethernet).
My first expose to free software was using RMS' account to login on AI, and reading the GNU manifest.
I'd argue quite strongly that Free Software was indeed unobtanium ...
