> Our system involves both an on-device component where the voucher is created, but nothing is learned, and a server-side component, which is where that voucher is sent along with data coming to Apple service and processed across the account to learn if there are collections of illegal CSAM. That means that it is a service feature.

Neuenschwander seems to, maybe deliberately, be conflating : "Apple's servers have to be in the loop" and "the code can only look at photos on iCloud".

You are right, the problem is a "slippery slope," but Apple just built roller skates and there are governments trying to push us down it. Apple is in a far better position to resist those efforts if they say " we don't have this code, we will not build it, and there's no way for it to be safe for our users."

I'd say that's a little different than the slippery slope. Something more like (in)defense in depth.
