The reason not everyone has the best watches, air conditioning, knives, or whiskey is that, for physical products, quality tends to cost more.<p>There is no reasonable argument to be made that people shouldn&#x27;t have higher quality products when they _don&#x27;t_ cost more^.<p>Apple only have to develop &quot;unbreakable&quot; encryption once and then it costs them no more to make it available in every iPhone than to only make it available in some of them. Indeed, it&#x27;d be cheaper than maintaining both breakable and &quot;unbreakable&quot; variants.<p>There are arguments to be made about the secure enclave hardware, since it presumably costs more to make it more tamperproof.<p>However, securing iPhones against this particular &quot;attack&quot; appears to be a software issue: iOS should never apply updates without an authenticated user approving them first.<p>^ For the avoidance of doubt, this includes externalized costs.
