What to say to people who say this kinda of thing? Usually I just say “ok then”
Some variation of the below:
Can I have your phone with the messaging apps unlocked?
Can I log into your personal email?
Can I see your tax returns?
Can I set up cameras and microphones in your house?
Can I place a GPS tracker on your car?
It also works with opening up the info to anyone, not just you. That’s one of the key issues, even if a trusted party is accessing the info there’s a chance that a malicious party can get access too. Or the trusted party becomes malicious later (government changes, company changes hands, etc.)
People generally don’t want everything in their home live streamed 24/7. If anything it has the potential for abuse, like if someone knows when you’ll be out of home for a few hours
Insurance companies in some countries give you a discount if you agree to put a tracker on your car…
Or use their app on your phone, which will “detect your driving patterns” and adjust your rates accordingly.
But honestly, even without all that, modern cars already have trackers and Internet connections even without your knowledge. (Mine did a couple of impromptu OTA updates for the media center at the beginning. It also has an SOS button on the roof, which you need to be subscribed to use, but can activate the subscription through the button. This implies there is a GPS tracker, as well as a cellular connection).
