I am really interested in this topic, especially because yesterday I was watching a BBC documentary about Aaron Schwartz.
I truly recommend this documentary not only because of the biographical importance of the story of Aaron's life, but especially because it makes you reflect about social justice and equality about the principles of Open Source.
Definitely Open Source resources can be a great advantage in inspiration, because everyone then is encouraged in building up their own knowledge for free. The idea of sharing from a bottom-up perspective is definitely exciting... But... On the other side, there is a systemic issue: most of the knowledge is not open. That means that there are systems still based on greed, a kind of "institutionalised criminal organisation" that is not interested in loose the privilege of keeping the access to resources closed or at least incredibly restricted to an elitist group of people.
Open source is not only a revolutionary way of sharing knowledge, but it's a philosophical, anthropological revolution too. I think that Open Source can make a difference, but of course this will affect - and actually it is still affecting - the secularisation of Institutions.
