Okay, first of all I highly doubt that this decision is permanent. Secondly, do you remember what happened after Columbine and 9/11? Shows (such as Buffy the Vampire Slayer) pulled episodes that contained guns or violence at schools (the Buffy episode aired later that year). After 9/11, dozens of movies, video games and even theme park attractions were pulled/modified. This is not a new thing.
Also it's kind of funny that the same people who say mobile games "are for casuals" are the same ones crying "censorship" now.
