In addition to the often cited freedoms of the free software—use, study, modify, distribute; the speaker also made parallels about the free software and science on the basis of free exchange on knowledge and thoughts; falsification and expansion principles.
According to me the take home point of talk was about the freedom that free software provides to its users in terms of archiving and preserving the knowledge for humankind. Software is emerging as a digital culture, but who is controlling this culture. To me this is the issue that needs a serious thought.
