>Are we going to need to reverse engineer every single Apple update to make sure the feature hasn't creeped into non-iCloud uses? Did we do this already?

Be angry at Samsung for their system. I don't blame Snap if I have a problem with Instagram Stories. >How are we sure the hash list isn't tainted? How did we know the hash list wasn't tainted when doing this comparison on Apple's servers? >All of these problems are solved by one principle: Don't put the backdoor code in the OS to begin with. Apple controls the hardware, software, and cloud services. The backdoor didn't need to exist in the OS for there to be a backdoor.
