Judging by the new CSAM legislation being pushed by EU bureaucrats, your fridge won't report to its maker but to EU commission and maybe to your own government.
So a fridge with very limited embedded storage doesn't really match.
I can't seem to find the relevant part of GDPR that would even attempt to cover that - beyond any tracking data sent back to the manufacturer.
Say you are Samsung, you have a fridge with a camera on it that keeps track of what’s in the fridge “for the user”, so they can see inside their fridge even when not at home. Now add in some image recognition, automatically tracking exactly what’s in the fridge, how often it’s used, when it’s running low. Now you have some of the most valuable consumer data possible to sell to data brokers. That is defiantly covered by GDPR.
France doesn't even have WiFi in schools for this reason. Hard to imagine they would allow something like this in a vehicle.
Also, use of your home internet modem to transmit a ISP-only open wifi is also legal according to many EU laws.
I can't count how many times my friends and family said "I don't care" when I tried to educate them on how their devices or software spy on them.
People who really care about privacy enough not to buy stuff that spies on them are rare, and becoming rarer every year as more and more kids grow up in a world where being spied upon is normal.
My expectation is the online tracking/advertising is about to hit an incredible hard legislative period. The change that is coming is big, and the fallout it going to seriously badly hit some business models and corporations.
However, you are completely right, they will try anything and everything to continue.
