Even if you do go to the builder, what are they going to tell you other than “yup. Lock got busted: here, here, and here, you should probably call the <people who investigate break ins for a living>”?
I feel like the notification already does exactly that, no? “Hey, your phone looks busted, go call the <people who investigate sophisticated cyber surveillance targeting for a living>.”
And from the angle of “yeah you guys installed the locks wrong and they just opened the door, you should fix that”- does anyone reject the idea that the vuln would get reported to Apple, and that they’d be on it like crazy?
