Why should norms and licenses be in any way mutually exclusive? Open licenses each have degrees of freedom, ranging from basic copy permissions to entirely public domain. Codifying and applying these licenses sets clear boundaries for users, helping them know what legal restrictions exist. Within these limits the community standards still apply, as a flexible and improving set of best practices. Either licenses or community norms are helpful separately, and combined their effects work hand in hand to provide freedom of usage and ease of access, along with guidelines to achieve the best results. Thanks for the nice discussion, still picking over all the articles =)
