I don't think I'd go that far. I mean it's pretty difficult to live without a smart phone these days. And there are easier ways to track someone. But yeah, both Google and Apple spy a ton. Google used to not so much of you opted out before they dropped the "don't be evil" thing and went pure evil. And at least with Android there are alternative operating systems like GrapheneOS that are way more private. But yeah, if you must have no tracking whatsoever, then don't own any electronic devices with any wireless capabilites since things like traffic cameras track you based on Bluetooth, NFC, and WiFi MAC addresses as well as license plates and they are super easy to hack the whole network and track anyone...which lead to don't own a car.

Anyway, it's nearly impossible these days to avoid being tracked. You have to isolate yourself pretty seriously to truly not be tracked.
