I also thought of calling this episode of our Four Freedoms podcast series "The interesting journey of a company producing proprietary software being involved in an open source project," ... not so catchy. Or maybe "Why business and openness do not have to be enemies." The point is that on February 12, 2013, Opera Software announced that it was dropping its own, proprietary rendering engine in favour of the open source WebKit engine. I wanted to know more about that decision and the consequences going forward. What I discovered is a company with a commitment to open standards, knowledge sharing, liberal licensing, and a long-term history of actions to back those claims up.
