Outreach Manager for OSU Open Source Lab What is the OSL? http://osuosl.org Tripartite mission: hosting major open source projects, providing training to student employees, outreach to help other organizations use “the open source way” Previously Google Inc responsible for their Summer of Code program, Google Code In (then GHOP) & launched dev blog
Who uses open source regularly? Those that didn't raise hands: Who uses Facebook? Google? Shops on Amazon? A little bit of history on the OSI – why they exist, approval of licenses
Explain who Richard Stallman is Recap the printer story: http://oreilly.com/openbook/freedom/ch01.html
Explain each of the four freedoms Explain in detail what each one means in real terms Discuss ways each freedom relates back to Richard's experience with the printer at MIT
There is a great deal of 'practical' information in the GPL and all software licenses – provided as is, warranty free, etc. Software licenses are manifestations of personal value systems Consider this is equally true in the case of corporate “personhood”
Fears of mixing in GPL licensed code and giving up rights to corporate created works Different ideologies made for difficult conversations – think back to Sproul and the NDA Seen to hamper innovation due to lack of adoption
Selling people on the same values as those that guided Netscape Linus Torvalds, creator of Linux, 'blesse' the term April 8, 1998 the community elders voted to begin promoting the term open source and adopt rhetoric of pragmatism & market-friendliness For quote, see http://opensource.org/history
Many, many years of arguing and consternation License incompatibility is a big source of issue; more than 100 approved OSI licenses at this time See book cover – image obtained from Amazon for this work Not particularly interesting but remember, this is a “religious” view for some people Licenses are an expression of people's value systems in addition to being legal documents
Discuss patent clause in Apache license and how it helps to preclude patent litigation Apache has had a great deal of outside contribution despite not requiring it – mention mainline branch maintenance vs. internal branches Consider again the notion of corporate personhood in context of software licensing: Google prefers Apache Eclipse project sponsored out of IBM and created their own license to go with the code base
Both ways have created excellent business successes Independent developers still largely value the GPL, with more than 50% of newly licensed projects on SourceForge and other hosting sites being GPL (this information is dated to around 2005, though, be warned)

The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works …. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
