Development of Creative Commons licenses

[Roger Chrisman <roger AT rogerchrisman.com>]

I heard mention of a "clarification" to the CC Non-commercial license 
element that allows advertising such as Google Ads. Anyone know more 
about this "clarification" and where it is written?

I looked for it in the CC Non-commercial license element but I don't 
think I found it there and the element seems vague and wide open to 
interpretation to me. Here is NC license element *4c* of by-nc-sa-3.0 
[1] (identical but for the typo "con-nection" to element *4b* of 
by-nc-nd-3.0 [2] and by-nc-3.0 [3]):

       "You may not exercise any of the rights granted to You in Section 
3 above in any manner that is ***primarily*** intended for or directed 
toward commercial advantage or private monetary compensation. The 
***exchange of the Work for other copyrighted works*** by means of 
digital file-sharing or otherwise shall not be considered to be 
intended for or directed toward commercial advantage or private 
monetary compensation, provided there is no payment of any monetary 
compensation in ***con-nection*** with the exchange of copyrighted 
works." (asterisks added for emphasis)


* What in the NC element clearly allows sites to sell ad space around NC 
content?

* Anyone know why the word "primarily" is used as a qualifier and what 
it could mean as such?

* Why mention "exchange of the Work for other copyrighted works"? What 
is that for?

* Why have the typo "con-nection" in by-nc-sa-3.0? Who can I email to 
have that typo corrected?

Any answers much appreciated.

I favor BY-SA licenses over NC licenses, myself, but I try to understand 
what's up when folks choose NC licenses and then put Google Ads on 
their site, too. 

Thanks!
