I still kinda like the restrictive takes of copyfarleft that prevents for-profit entities to use anything without contributions. Workers, co-ops, nonprofits do not have any of those restrictions.

My biggest issues with those licenses are specifically that they are & never could be GPL-compatible which would encourage permissive licenses for libraries which is part of what both license types want to avoid.

Has anyone gone so far as to dual-license under copyleft & copyfarleft?
