For me, it boils down to the fact that I don'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'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't modify it without invalidating the code signature. The FBI could post the code on Facebook and it wouldn't make any difference, nobody would be able to use it.

With that in mind I find it ridiculous that Apple is refusing.

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's what is going on, but it's not. The FBI is asking Apple to exploit a vulnerability that already exists in an older operating system.

If Apple cared so much about user security then that vulnerability wouldn't have been there in the first place.
