Ethical Licensing

Soon after I first learned about open source and free software license, I started wondering about what sort of clauses could be added to licenses. Recently, I've become progressively interested in licenses with morality clauses in them.

I'm starting a list of the licenses (and their relatives such as Terms of Service) I come across that contain apparent ethical clauses. You can find these under the ethical-license label.

Here is a general Stack Overflow question on this topic; another on the relationship to OSS. Looking forward to exploring this topic with you.
