2018/08/29: something called the Lerna project has added a codicil to its MIT license denying the use of its software to a long list of organizations because it disagrees with a political choice those organizations have made.
Speaking as one of the original co-authors of the Open Source Definition, I state a fact. As amended, the Lerna license is no longer conformant with the OSD. It has specifically broken compliance with clause 5 (“No Discrimination Against Persons or Groups”).
Accordingly, Lerna has defected from the open-source community and should be shunned by anyone who values the health of that community. I will not contribute to their project, and will urge others not to, until and unless this change is rescinded.
We wrote Clause 5 into the OSD for a good reason. Exclusions and carve-outs like Lerna’s, if they became common, would create tremendous uncertainty about the ethics and even the legality of code re-use. Suppose I were to take a snippet from Lerna code and re-use it in a project that (possibly without my knowledge) was deployed by one of the proscribed organizations; what would my ethical and legal exposure be?
