I believe that the relevant use cases are #5 and #6 as listed here: http://www.w3.org/2011/03/html-license-options.html#usecases At the moment, the FSF is not alone in declaring CC-BY incompatible with their license, the Mozilla Foundation has come to a similar conclusion: http://www.mozilla.org/MPL/license-policy.html The ASF hasn't concluded its analysis, but seems likely to agree: https://issues.apache.org/jira/browse/LEGAL-167 Some of the clauses in the CC-BY license cause trouble not only for "Free" Software Vendors, but commercial/proprietary vendors alike. Examples: * You may not offer or impose any terms on the Work that restrict the terms of this License or the ability of a recipient of the Work to exercise the rights granted to that recipient under the terms of the License. * You may not sublicense the Work. * You may not impose any technological measures on the Work that restrict the ability of a recipient of the Work from You to exercise the rights granted to that recipient under the terms of the License. Finally, I'll note that the authors of the CC-BY license themselves don't recommend this license for software: http://wiki.creativecommons.org/Frequently_Asked_Questions#Can_I_apply_a_Creative_Commons_license_to_software.3F > --Wendy > > [1] http://www.w3.org/2005/10/Process-20051014/process.html#dissemination > >> Kind regards, >> >> -- >> http://annevankesteren.nl/ - Sam Ruby
