Does this mean every parent has to now make sure not to take pictures of their children playing in bath for instance, in order not to trip these scans for false positives?
They CLAIM they scan for CSAM, so watch out your documents and pictures with something that govt also wants to track.
Even with e2ee enabled for iCloud Photos/files (which NOBODY uses, and furthermore is entirely disabled in the UK), it sends identifying hashes of plaintext file content to the server without e2ee.
