I've already written this in a previous comment, however I think it bears repeating: I think Apple have introduced this client-side content scanning technology under the auspices of protecting against CSAM, while its true intention is to allow for the Chinese government to scan citizens' phones for subversive content. I'm convinced that Apple's upper management figure the minimal blowback they're experiencing for this privacy invading technology in the west is worth the expansion of their technology into a much more totalitarian Chinese market. I think that this development has been precipitated by a very visible decline in America's economic, and social position as a world leader. Why not risk this move? America's trajectory is that of almost definite decline.
