I've been persuaded on this over the past few days.<p>Initially, I saw the controversy as overblown: It's the exact same content scan that already occurs when uploading images to iCloud; it will still only occur when uploading, and the only change is where it takes place.<p>I now see that as a reductionist take. Where it takes place <i>does</i> matter. The lines between client and server have been slowly blurred over the past decade to the point where a move like this may seem trivial to many, but ultimately, it is not. It becomes a foothold for so much more, and despite Apple's detailed assurances of all the friction they've installed onto this particular slippery slope, to step onto it at all is a step too far.
