Mahitgar, sorry but I still do not get the context. As far as I know, the servers of the mr.wikipedia as well as commons are hosted by the Wikimedia Foundation out of USA and is entirely under US copyright jurisdiction; and all content on the servers only need to fulfill the requirements of US law.

In any case I think CC0 and PD represent the extreme of freedom that, based on my personal interactions with artists and photographers, few private individuals in India would consider. Most individuals seem to prefer a cc-by-nc-nd. A 2009 study by Creative Commons shows that on Flickr, the restrictive licenses are more popular (less than a quarter are Commons compatible) - http://creativecommons.org/weblog/entry/13588

This does however raise an interesting question on whether Indian/Indic users make an intelligent choice of licenses when uploading on Commons. For a general idea of the break up of files by license-type - see the figures in https://commons.wikimedia.org/wiki/Category:Free_Creative_Commons_licenses - the numbers indicated here are tricky as a single file can be under multiple licenses. However this should give some sense on license popularity and tell us where educational efforts are needed. PD and CC0 represent under 5% of the files.
