Again, nothing except photos you uploaded to iCloud was to be scanned. Apple's plan was to have your device conduct the scan and encrypt the scan results so not even they could see them until a threshold of ~30 image matches was reached. This protects the user from false positives. Once the 30 image threshold was crossed, the plan was to have a human review before turning someone into the authorities. I think we all know that Google is not ever going to hire expensive human beings to supervise it's algorithms, so a single false positive would likely see you turned in for kiddie porn.

> nothing except photos you uploaded to iCloud was to be scanned. My point is that the difference between the approach from Google and Apple is that in one case (Google), we have a tech level blockage, it's not currently possible for Google to even do that. On the other hand (Apple), the "blockage" is policy or "promise". That's far less reliable than the tech just not existing.

They can stick it into the binary blob of closed source Play Store code, and you would have no way of knowing it is there. Google still does scan everything in your online account and has been doing so for the last decade. Apple has backed down from even doing that for iCloud Photos.
