RRResearch: Informing authors of the real consequences of CC-BY open-access publication

"Thanks to comments on the previous post, I now realize that there have been extensive discussions of the merits of different CC licenses for open-access publishing.  See for example: http://oaspa.org/why-cc-by/. These discussion explain that the most open licenses are best for the dissemination and utilization of scientific information. That's probably why both PLOS One and BioMed Central use only the CC-BY license, which allows unlimited use and modification, including commercial uses, provided the source is attributed.  At a minimum the attribution requires listing the names of the authors.  It should also require citing the journal where the article appeared, although this isn't always clearly spelled out.  But, as the previous post and a related post describe, the CC-BY license creates new problems for authors, because some for-profit publishers have begun aggregating CC-BY papers into high-priced edited books without the authors' knowledge.  The authors I've discussed this with are quite upset.  They trusted the journals to offer licensing arrangements that were in the authors' best interests, but now they feel that they have relinquished control of their scientific reputations.  (Note that these weren't predatory publishers, but PLOS One and BioMed Central.)  Most of the discussions of open access licenses haven't considered the exploitation of these licenses by for-profit publishers, probably because this niche opened only very recently, once open-access papers became widely available.  I and others discovered this problem by accident.  I don't know how widespread it is, but I expect it will only grow.  (I'd like to do a survey of its prevalence, but I can't figure out any way to distinguish between such repackaged books and traditional multi-author volumes without having to contact individual authors - any suggestions?) ... In some ways the ethical issues are like those of a clinical trial.   Participation generates a public benefit (medical research) and may be directly beneficial to the participant (better medical care, access to new therapies).  But the researchers directing a clinical trial are obliged to make sure that potential participants also understand the risks and costs.  They can't assume that the participants have thought the implications through, but must spell these out in clear and simple language.  Similarly, advocates of open access need to honestly inform authors about the consequences of the CC-BY license.  The onus shouldn't be on the authors to research the implications and consequences of different licenses, but on those with expert knowledge to communicate this to the authors.   So, two questions:  [1] Should authors in open-access journals be allowed to choose between different CC licenses?  Publishers agree that CC-BY is best for science, but authors may think it is not best for them. The major publishers don't give authors any choice, but I think they should.  [2] How should open-access journals inform authors about license consequences?  This is particularly important when CC-BY is the only or default license.  Most scientists I've talked to are unaware that the CC-BY licenses of their open-access papers allow commercial publishers to alter and republish their papers without consulting them.  And they are very unhappy to learn that this is actually happening, often saying that they'll have to rethink their use of open-access ..."
