That is an incorrect assumption, I am also well aware they are not talking about CSAM. Thanks.There is. You just didn’t read it. Apple has documented both these systems in great detail, even including a technical paper describing the exact algorithms for the CSAM detection (which we are not talking about here).
There are still questions, and like some Tech security analysts have discussed Apple's details are a bit vague and read more like Marketing than actual details on what is happening on the devices. This thread, Posts on Reddit, and other forums seem to strongly indicate that their (even updated) message has not come across correctly or that well.
Again, not against either technology (even the CSAM not being discussed here), just feel Apple can spend a bit more time / marketing / whatever, to get their message out.
