Lots of interesting discussion on ethics-based licenses. I think it's something we need to think about.
Unfortunately I also think they're going to prove ineffective and harmful. Ethics-based licenses are great when the ethics map to your own ethics. But what happens when someone declares that their software can't be used by "people like you" (whatever that might be). Then you're trying to use a license to weaponize your beliefs in your software.
Be careful out there.
