It seemed clear they were making moves in this direction back when their announcement about on device hash checking for CSAM prior to iCloud photos backup was made. That announcement only made sense in a world where they wanted to enable end to end encryption for photos. It's cool to see them do this, and see them also extend it to Messages too (surprising imo). -- > The apple policy was likely about coming up with a way to enable encrypted photos on iCloud while still having some privacy preserving form of CSAM detection. Since it was only enabled when iCloud photos was enabled it was better for privacy on net than the status quo (unencrypted iCloud photos that are accessible to apple and scanned anyway). https://news.ycombinator.com/item?id=30297272 https://news.ycombinator.com/item?id=30297272
