I note, with considerable disappointment, that the Noora wallpaper depicts a woman committing a sin against God - she has no scarf! No burka! And this during the Holy Ramadan season! Oh, the humanity! Will no righteous believer give that woman a scarf? Infidels! 
On a more serious note, popular media is a powerful tool for social control and behavior modification. The youth, often with malleable beliefs, are a good target. Done the right way, deep change might be insinuated into the religion.
Information, nicely crafted, can be a more effective way of destroying group B (however defined) than most alternatives. YMMV, IMO.
