I'll bet on #1. If this was a PR stunt, it didn't benefit any of the Big Tech firms. Marketshare of Linux and De-googled Android just went up a bit. My Apple devices will likely go to friends and family that want upgrades and won't leave Apple. I probably won't be buying replacement devices. Right there is an easy $3,000-$4,000 of lost future sales, plus the loss of my iCloud and Apple Music subscriptions.After learning about these new features (as best I can), more and more I am coming to the conclusion that this is either:
1. This is part of a bigger system Apple is designing and using “CSAM” as the excuse to kick it off
or
2. All a big PR stunt by Apple in an effort to encourage folks to stay in the Apple Garden (away from FB and Android)
Apple's scanning system, by design, puts a lot of trust in their two "sovereign" sources. Apple themselves have little verification that the system isn't being abused until a lot of non-CSAM content is flagged for human review. Our only protection at that point would be the human reviewers hired by Apple.
