Non-zero being technically true because of the subject matter, but I don’t see how Apple’s system increases the risk of authorities killing family or pets more than server-side scanning.
False dichotomy. How about they leave people's data alone?
A lot of innocent people are going to get caught up in this.
I think some people think that’s the probability of a picture being incorrectly flagged, which would be more concerning given the 1.5 trillion images created in the US.

"The threshold is selected to provide an extremely low (1 in 1 trillion) probability of incorrectly flagging a given account. This is further mitigated by a manual review process wherein Apple reviews each report to confirm there is a match..."
So it's 1 in 1 trillion per account PRIOR to manual review in which the odds of error get reduced even further.
Photos in iCloud are unencrypted and Apple checks for CSAM on the unencrypted photos server side, they know of all matches.
OR
Photo hashes are checked client side and only if a certain threshold of matches is passed does Apple get notified at all (at which point there's a sanity check for false positive by a person). This would allow all photos on iCloud to be able to be encrypted e2e.
Both only happen when iCloud photo backup is enabled.
The new method reduces the risk.
