From the press release on the just-released SPARC Europe report copyright and licensing policy [pdf]:

Clear from this study: the majority of publishers have yet to embark on a more OA friendly policy journey, though some are making preparations. “If these publishers choose to continue on their current course, their authors will continue to find complying with OA policy requirements problematic — unless funders change their grant conditions and/or institutions/authors retain their rights,” wrote the authors.

The whole report is worth reading, but of special interest are the recommendations, which lay out best practices for foot-dragging publishers (and other stakeholders). Still, SPARC Europe’s fixation on CC BY—part of a wider CC BY fetishism in segments of the OA world—is frustrating. There are good reasons to encourage non-commercial OA licenses like CC BY-NC: to block commercial exploitation and to encourage a nonprofit scholarly communication ecosystem.
