An Open Source License That Requires Users to Do No Harm

Open source software can generally be freely copied and reused. One developer wants to impose ethical constraints on the practice.

"Increasingly, some developers are calling on their employers and the government to stop using their work in ways they believe are unethical...

Coraline Ada Ehmke wants to give her fellow developers more control over how their software is used. Software released under her new "Hippocratic License" can be shared and modified for almost any purpose, with one big exception: "Individuals, corporations, governments, or other groups for systems or activities that actively and knowingly endanger, harm, or otherwise threaten the physical, mental, economic, or general well-being of individuals or groups in violation of the United Nations Universal Declaration of Human Rights.”

Defining what it means to do harm is inherently contentious, but Ehmke hopes that tying the license to existing international standards will reduce the uncertainty. The declaration of human rights "is a document that's 70 years old and is pretty well established and accepted for its definition of harm and what violating human rights really means," she says."
