We have been open source from the beginning, in 2004. Here are some current statistics about the state of our project since it was first published in Sourceforge, (now we work with Github). Open source is not just a license or a way of thinking, but a form of software engineering for sharing knowledge and implementing continuous improvement cycles. The statistics below were gathered in June 2016. You can find more updated statistics on Github and OpenHub.
