Regardless, whether or not you allow Russian users to download apps is an independent question or whether or not you allow anyone to download these particular apps. As I understand it Apple's action is world wide. It does appear that the apps in question are still available from Google (though I didn't try installing them...) [2]

And the length of the Wikipedia article (https://en.wikipedia.org/wiki/Kashmir_conflict) strongly suggests that this is a controversial point of view ;-)
