Enabling more anonymity, when desired
Version 3.0 included a provision allowing a licensor to request that a licensee remove the attribution from an adaptation, if she did not want her name associated with it. Version 4.0 expands that provision to apply not only to adaptations but also to verbatim reproductions of a work. Licenses now account specifically for situations where licensors wish to disassociate themselves from uses of their works they object to, even if their work hasn’t been modified or published in a collection with other works.
