Open source software revolutionised how software developers build products. Tech companies around the world are now built upon their use and contribution to open source. Github lists more than 25 million public projects — the project with the most public contributions? , a project owned by Microsoft, who’s CEO once described open source as a “ ”. VS Code cancer Many of the individual developers that contribute to this free and open code base that tech giants build their success upon, do so in the hope of making a better world. Just ask the Apache Foundation. Started by a group of open source developers maintaining the most popular web server of the last 20 years, the charity foundation was created to assure that their resources would be used for .

Open source software is built on the idea of freedom, yet many of the most well known open source projects are being used to strike at the very heart of our freedoms — even the freedom to consciously choose our own behaviour. The open source movement is an incredibly generous and inspiring one: Github has recorded over public contributions to open software. The time has now come for us to start setting limits on the exploitation of that generosity to attack our freedoms and our future. a billion At , we place purpose at the centre of what we decide to work on and who we work with.

The license restricts the use of the code to promote or profit from violence, environmental destruction, abuse of human rights, and the destruction of people’s physical and mental health. Just World License Of course, this is not a silver bullet. It’s not even a bullet. The challenges of how we use the tech we build ultimately isn’t something that has a technical or legal fix. It requires us as developers, and as a society, to decide to set hard boundaries on the use of tech in ways that harm people, our planet and our future. Just as the divestment movements have helped to revoke the social licenses for apartheid and fossil fuels, it’s my hope that the Just World License will contribute to a rethink of the boundaries that we set for acceptable use of software and technology in our society. It’s also my hope that this will contribute to a change in culture around software development. Just as the open source movement revolutionised the way we think about how developers build, collaborate on and share software, the revelations of how that software is being used highlight a need for us to rethink we write software, what it should be used for, and what limits we as developers place on how our work is to be used. why These are not easy questions to answer, but the first step to answering them is having a framework to think about what we want our software to be used for.
