How do you know they haven’t secretly rolled it out? They can easily run it in the cloud without an iOS update. Or even sneak it in an iOS update, because last I knew it was closed source and not open source code.
Re: 74 - That’s always possible but I consider it unlikely. I believe that would be caught by developers or security consultants. But I guess they could all be in the scanning as well and compelled or threatened to say nothing.
If Apple rolls out CSAM, I believe they will announce it and let people make their own decision. That’s less apt to be constructed as nefarious than rolling it out clandestinely.
Good luck!
