Nope. If scanning was implemented outside the device on the iCloud as everyone else, may be. But this is intrusion of privacy on a new "on device surveillance" level and Apple deserves hostile reaction.

No form of apologetic or "technical" explanation can remove this from reality now. They are betting heavily on their "core" demographics to trust them automatically and without any form of critical thinking.

If this implementation has no effect on Apples bottom line. Things are over. We will live in badly implemented version of the Minority Report.
