What is the practical roadmap for current Apple users who want to escape from this privacy boondoggle. I'm a longtime Mac and iPhone user, but will be switching all of our family's devices by the next upgrade. My only question is what is the timeline? Do I need to get new devices by next week, or is there time before this is put in place? And in the interim what can I do within the Apple ecosystem to minimize my privacy attack surface area from CSAM?
