Backdoors are just bad news for everyone, and I think Tim Cook nailed it when he said,
We can find no precedent for an American company being forced to expose its customers to a greater risk of attack. For years, cryptologists and national security experts have been warning against weakening encryption. Doing so would hurt only the well-meaning and law-abiding citizens who rely on companies like Apple to protect their data. Criminals and bad actors will still encrypt, using tools that are readily available to them.
The FBI is pretending, and to a certain degree may honestly and naively believe that people outside of government have no need or requirement for this level of security on their data. We do, and we must. Apple must not be compelled to compromise their own security framework for the sake of identifying a terrorist network. That puts all of us at risk. We didn't sign up to do the FBI's job for them. If they have no HUMINT then its a government failure. Let the FBI find the terrorist network. We really hope they can, but millions of citizens, buyers of Apple or any security system, shouldn't have to pay the price and take on risk against the possibility that there is extraordinary risk to a few citizens in the long term. That's not our job.
