Open Source and the Open Usage Commons, with Chris DiBona

An open source license grants rights on copyright and patents, but not trademarks. Chris DiBona has some ideas on how to address that.

It launched last week with three projects - Angular, Gerrit and Istio - transferring their trademarks. Chris joins Adam and Craig to talk about Google’s work in open source, and why a new organisation is needed.
