Are you unable to answer any of the questions I asked? I'm seriously interested in hearing, from people who think Apple is in the wrong, where the border of acceptability is.

Would you prefer iOS submitted the photo's to their cloud unencrypted and Apple scanned them there? Because that's what the others are doing.

iCloud photos are not end-to-end encrypted, Apple has full access to them. https://support.apple.com/en-us/HT202303
