I think they use it in the sense Wikipedia = Encyclopedia (they are covering
India related news). Like Xerox machine became synonymous with photo
copying.
People might even mistake any wiki for Wikimedia projects. Probably there
are 100s of sites like this all over the world.
Unless someone is misusing Wikipedia trademark intentionally, we better let
them go off. An NPO like Wikimedia should not waste its resources in petty
issues.
