More or less correct if fully trusting any signed code by a third party (Apple) is a backdoor. For what it&#x27;s worth, signed code imparts security benefits to Apple and Android users who indeed can&#x27;t be trusted to not screw up their own phones.<p>Thing is, this entire system is based off of trust. If people lose trust in Apple, then they lose trust product. While even Apple can&#x27;t decrypt the data, existence of malicious signed code means you can&#x27;t trust signed code.<p>FBI would have done better to ask Apple in secret. Apple really made the only possible choice when faced with a public request.
