how do you define "spies"? As that could apply to pretty much any phone (smart phone or not, the cellular provider (and almost certainly the government)) tracks everywhere you go, modern TV's, cars, and many modern appliances have some degree of spying built in.
In this case, if you haven't been following this CSAM scandal and making use of iCloud as usual, should Apple turn this enigma machine on, you don't know your device is being used to spy on you.
Am sure Apple will employ the best brains to craft some form of legalese to make sure you tick the "accept" button without fully understanding what it means in the event they roll out.
What about your smart refrigerator - you might expect it to report refrigerator data (temperature, door openings,etc), but would you be surprised if it's also reporting your bedtime, wake up time, and when you're on vacation?
Do you know how long the cell phone company retains your location data, or what they do with it? Do most people even know the cell phone company tracks their location?
Many appliances spy on us in ways we don't know.
Personally, I live a simple "non-connected" life as much as I possibly can. Any service providers I choose to entertain have to do with the minimum required information to hold the account.
