1. allow MITM decryption by a privileged authority
2. require all devices doing E2EE have a non-user-modifiable piece of functionality to scan on-device
The second is the Apple style on-device CSAM scanner? I have to say that I do sometimes think about it while taking a photo of my baby playing in the bathtub - photos like my parents have of me which have been kind of nice to see later. It would be a pity if I had to have a separate analog camera just for baby photos because then I'd need to learn the whole developing film stuff.
