For me, it boils down to the fact that I don&#x27;t understand why Apple would not have the ability to restrict this exploited version of iOS to only run on the device in question.  That&#x27;s the entire point of code signing.  They could have the OS refuse to execute on anything other than that specific device, and the FBI can&#x27;t modify it without invalidating the code signature.  The FBI could post the code on Facebook and it wouldn&#x27;t make any difference, nobody would be able to use it.<p>With that in mind I find it ridiculous that Apple is refusing.<p>If the FBI was asking them to leave a vulnerability open in all versions of iOS that only the FBI could access, then I would have a huge problem with that.  Apple seems to want everyone to think that&#x27;s what is going on, but it&#x27;s not.  The FBI is asking Apple to exploit a vulnerability that already exists in an older operating system.<p>If Apple cared so much about user security then that vulnerability wouldn&#x27;t have been there in the first place.
