I have been searching for an open source license to use for my project. There are many little things i would like to have but only one thing that truly matters - I don't want anyone to use my projects libraries or the project itself to build something that they can then patent.
This is because the project is a charity about supplying free services if they are deemed essential or a basic human right. So it will not do if a third party creates, for example, a medical tool that they charge for, and then prevents us building a free alternative.
On the other hand, we do want a third party to do this if they themselves are looking to give their service for free as it reduces our work load. I could talk you through licenses I have considered thus far but perhaps its better to let you answer free of influence.
