So they’ve developed the technology and had planned to enable by default etc, following a backlash they’ve paired back the deployment and made it Non trivial to access and scrutinise, so it’ll be on everyones phone (likely already is) but only a vastly smaller subset will be able to enable it and it’ll go largely unnoticed by the majority.
the notification function is the bit that alerts users that the scanning feature is there but in all likelihood the feature could be enabled, scanning in the background, just the reporting is disabled by the options, we would be none the wiser but apple would get that telemetry data to help the, refine the process for a later date when they can then tweak it and try and market it as a feature again.
it’ll of course be used as a stepping stone to their mandatory scanning of all your photos For csam.
we all want to stop csam, but I don’t want to be spied on like this. We pay taxes for police services to stop anti human behaviour like csam, we don’t pay apple to do that, but I’m happy for apple to provide tools to police services to help in their efforts to combat these things, but it should be focussed and targeted at the criminals not everyone including the innocent law abiding citizens.
