Woops, you're right, thanks for the correction. I think the issue is that, as Ben Thompson pointed out, the only thing preventing them from scanning other stuff now is just policy , not capability , and now that Pandora's box is open it's going to be much more difficult to resist when a government comes to them and says "we want you to scan messages for subversive content".
Yes, of course that is true. I use iCloud Photos and find this terribly creepy. If Apple must scan my photos, I'd rather they do it on their servers. I could maybe understand the new implementation if Apple had announced they'd also be enabling E2E encryption of everything in iCloud, and explained it as "this is the only way we can prevent CSAM from being stored on our servers."
Why is that supposed to be their responsibility?
Given the scale of their business, there is effectively a certainty that people are transmitting CSAM via Comcast's network. That's no excuse for them to ban end to end encryption or start pushing out code to scan client devices.
When you hail a taxi, they don't search you for drugs before letting you inside.
Because they're not the police. It isn't their role to enforce the law.
