So who are the geniuseswho will disconnect it?
I am not sure I get your question. My 2021 Ford WANTS me to connect it to the Internet. It BEGS for a smartphone connection or WiFi connection. I had little choice in what I bought, but I only wanted a truck, so I give it no connection.
I have zero doubt that if I connected it, it would downgrade its software and violate my privacy six ways to Sunday. You are correct, that I would have to be a "genius" to disable all possible connection and retain a functioning vehicle, I expect.
