- ‘Innumerable questions surround the distribution of technical information in the copyleft environment, particularly because the Free Software Foundation has a copyleft license for its documentation as well.’
- ‘Applying the three-paragraph copyleft statement to tens of thousands of files was no easy feat, but we managed to automate it.’
- ‘The open source movement with Linux, Apache, GNU, and so forth said no, the way you really get creativity is by replacing copyright with what they call copyleft and hence replacing private property rights with a vibrant public domain.’
