And MY point is that if you're really concerned with that you never should have been using iCloud sync in the first place. You were already exposed to that risk.
But the CSAM technology won't be limited to photos uploaded to iCloud. That's where it starts, not where it ends. This technology exposes all users of iOS, past and present, to the whims of the current definition of "legal".
So your argument is that I should be concerned because they may change the feature to do something different than it does now. But you could always say that. They could make it do anything in the future.
True, at some point you have to trust someone, whether it's your phone's manufacturer, your telco, or the developers of the apps you use. But when there's a flagrant disregard for users and the potential impact a system like CSAM could have on them, to me that crosses a line and means the company is no longer trustworthy:
> If a company actively screws its users in broad daylight, then what's going on behind closed doors?
At least previously Apple had the pastiche of a privacy and user-centric company. No more if this goes through.
