Missed this during the election week: Apple have apparently turned down an Atari Teenage Riot app lest it be used to create riots. Alongside the songs there was sounds of an actual riot, which, apparently, could be bad:
According to a press release, those sounds include "very low sub basses, square waves, noise sounds which trigger hysteria and panic within the audience." So your iPhone could make a whole lot of people very uncomfortable, if hooked up to big speakers-- which ATR encourages, via press release.
It's not that Apple are worried about the social implications, but 'making a horrible noise which gives people the willies' is covered by a patent that Justin Beiber holds.
