That's because people don't understand how technology works.
They think this is some kind of new system that gives Apple new access to things. It's not. They access they have here is nothing compared to what they have always had.
They can and do scan all your messages and photos already, locally, for features such as photo classification and making reminders from emails.
Apple could spy on anything they want, without this system. And this system is an incredibly impractical way to spy on people.
It's also pretty obvious that they wouldn't tell us if they were planning to spy on us, they would just do it.
In short: I have no idea if Apple spies on us, but I can say for certain that they will not use this system for it.
