Shea, Tom (23 de junio de 1983). «Free software - Free software is a junkyard of software spare parts». InfoWorld. Consultado el 10 de febrero de 2016. «"In contrast to commercial software is a large and growing body of free software that exists in the public domain. Public-domain software is written by microcomputer hobbyists (also known as "hackers") many of whom are professional programmers in their work life. [...] Since everybody has access to source code, many routines have not only been used but dramatically improved by other programmers."».
