What people don't seem to understand is that this is not going about child pornography.
The technique is basically this, that anyone who wants to (or can do in Apples eyes) can send Apple hashes of pictures, text, voice etc. and the new system will scan silently all iphone users on the globe.
So lets say i am a dictator. I want anyone to drink cola, people who drink just plain water are subhumans to me. I know you are an political opponent, or whatsover, and i know this, because you came public with your disagreement in a viral video. I take your picture/video screenshot and/or your voice from the interview, make a hash file of this and Apple will tell me if you are one of their users, and if you are, what your name is, where you live, and so on.
And Apple will tell me all his global users who have your picture, text, audio or video, i will know how many people know this guy or are in contact with him.
With all this information, i can take my police or others to hunt you and all the others down. Or i do this silently, just to confirm the data, and then i send drones to shoot you from the skies or fire a rocket on your house.
This is not science fiction, all these techniques do already exist. But yet there was no Apple or Google who implemented the last puzzle piece to make this dictators dream come true.
Apple was so to say the last one who could prevent global dictatorship. And they decided to let this happen now. Once this is implemented, everybody will be a possible target to his government or even big tech companies, if they take over more and more government tasks.
So you have to decide if you want to pay with your freedom for using smartphones, or if you will throw your smartphone into trash to keep your freedom.
We all must decide this now. It is elementary!
