Ask HN: Open sourcing my project, how to enforce the “social” license I chose?
I'd like to license everything (code, marketing and legal materials...) under an open source license which with a clause by which the restaurants that use them have to donate at least 5 dollars per month to non profits. The non profits should help finance similar projects, hopefully creating a virtuous cycle of socially responsible code and businesses.
There are more details to how this would work but that's the gist of it, to create a "social open source" project that would encourage the creation of others
What is holding me back is that I do not know how I could enforce such a license. I have created the project on my own with little means and I would have no way of knowing who is using the code to create their own products. I've thought about several alternatives:
1) Giving the ownership of the code to an organization that would have the means to enforce the license. I suppose there could be organizations interested on fostering this kind of project.
2) Keeping the backend code closed so I could know which restaurants are using it and make sure they do the donation to the NGO. There are downsides to this approach from my lack of previous reputation to server costs.
Are there other ways to make sure a license is complied with?
* The product is described in www.alfiv.com, it is used by restaurants in Spain and France and everything (UI, legal terms, marketing...) is translated to English, French and Spanish
I've used a common software stack (react + redux + ramda) in order to facilitate collaboration
* I chose the restoration industry because of its size, if a "social open source" project could become an important player in this field with this kind of license it could allow the creation of many other similar projects
