This is a joke, right? Tim Cook is on an anti-privacy spree, using some ridiculous "children protection" slogans as a pretense for invasive, user-hostile changes.
Tim Cook is actually completely right to offload scan from the servers to client devices. As a little clueless man you just don't understand world you live in. Every "digital" business is oblige to spy ànd report you by laws you hardly understànd made by people you never elected. People you will never know exist from departments that's ring no bell can request your location, video recording of your from thousands of cameras, your call recordings, your chat logs and all your photos "protected" by 2FA and "encrypted" all from single convinient UI. You have no privacy. It is too late. You can deny it, and this is ok, while you pay taxes and not asking questions. What happen to you if you start making problems to them?
