De Gruyter Open has released "The Mystery of Creative Commons Licenses" by Witold Kieńć.
Here's an excerpt:
While more than half of open access papers are published under the terms of a liberal Creative Commons Attribution Licence, the majority of authors of open access works seem not to accept the terms of either this or any other Creative Commons license.
Despite the fact that the majority of journals indexed in the Directory of Open Access Journals use liberal Creative Commons Attribution (CC-BY) licence as a default, and that probably more than half of all articles published in open access serials are published under the terms of this licence, academic authors seem not to support liberal licensing. How is it possible? Are authors of more than 600 thousand CC-BY licensed works invisible in surveys? Or do they publish under the terms of this license against their will?
