Free beer...um, well I mean open source beer. Check out Harry Lanman's article from the February 18, 2007 Boston Globe about a group of students and artists that are producing and marketing the first open source beer.
They got the idea from discussions about open source software. Open source software producers maintain that customers live with software and use it regularly, so they should be able to tweak it and work out the bugs. Standford Law Professor Lawrence Lessig, the champion of open source software has written extensively and eloquently on the subject.
The Linux operating system and Mozilla Firefox browser are two examples of successful open source software. Richard Stallman, who manages Linux licenses once opined "think of 'free' as in 'free speech,' not 'free beer.'" He and others understand that software costs money to make and that one should be able to recoup those costs to pay the bills. However, they maintain that the knowledge that went into it should be free and shared with the public.
When the students announced their open source beer, they called it "free as in free software."
