Have any far left/anticapitalist licenses (#PeerProductionLicense, #AntiCapitalistSoftwareLicense, others? link me to em) been tested in US courts? Are there any legal or social organizations actively defending them? I don't know much about FOSS licenses, but I'm under the impression that without these a license is little more than a polite request (or perhaps one backed up by only a rude gesture). Is my understanding accurate there, or is there more to it?
