You are prohibited from creating missiles, chemical or biological weapons.
You also agree that you will not use these products for any purposes prohibited by United States law, including, without limitation, the development, design, manufacture or production of nuclear, missiles, or chemical or biological weapons.The wording of that (these products) implies that Apple may have inserted that paragraph into the TOS for other products.
In addition, it seems this is just a rehash of a previously humorous discovery. This clause was highlighted back in 2009 by Gizmodo. Comments on that story noted that some end users had seen the same clause brought up one or two years before
Still, it's a good time to bring up that age-old rant: TOS agreements are too complex and long, and given that, it shouldn't surprise anyone about the things that are in Terms of Service agreements that no one ever finds. Most people don't even bother glancing at them, at least not any longer than it takes to find the OK or Agree button.
That's precisely the good point made in the "Humancentipad" episode. It was the premiere episode of the fifteenth season of "South Park," and the 210th episode of the series overall.
Kyle, who did not read the Terms and Conditions before agreeing to his last iTunes update, is pursued by agents from Apple. Steve Jobs eventually turns Kyle and some others into a Humancentipad (parodying the horrific "Human Centipede" film and TOS agreements in one fell swoop).
The episode also debuted around the time that Apple was in hot water for a newly found location tracking file in iOS, and mocked that issue, as well.
