[cc-licenses] Possible way to subvert the intention of CC-BY-SA and other BY licenses

This issue is unfixable.  The author always has the power to waive a  
condition of the CC license.  Even if these clauses didn't exist, Eve  
could still use the picture in a highly offensive collection published  
CC-BY-SA.  Bob, outraged and upset, contacts Eve.  She says, "I'll  
take your name off if you let me use the picture free of any CC  
license at all."  Bob, desperate not to have his name on the  
collection, agrees.

These two clauses don't create this issue, which is inherent in the  
nature of a CC license -- it permits some uses the author might not  
necessarily agree with.  Instead, these two clauses help even out the  
relationship by making attribution not just waivable (which it always  
necessarily is) but actually forbidden if the licensor objects.
