I’m not claiming iPhones are superior. I don’t care about dumb OS wars, just don’t put things on your phone expecting that they can’t be retrieved. That’s the only point I’m trying to make here.
And the keys absolutely would give them access since those keys are used to sign Apple software which runs with enough privileges to access the encryption keys stored in the “Secure Enclave”. Anything you entrust to a company’s software is only as secure as the company wants to make it, and the only company to publicly resist granting that acces is Apple (so far)
The only thing that has successfully managed to thwart the FBI in their attempts to break into a phone was Apple’s hardware based encryption. To such an extent that they took legal and legislative actions to try and circumvent it. The specifics of how the encryption works is irrelevant to this argument, and you are more than welcome to consider that point conceded.
