Trivial to prove that, just set up an open wifi and show it connecting, getting an IP, and then transmitting data.
I haven't managed to reproduce it.
I've seen this "yeah well they'll just connect to open WiFI" for 10+ years at this point and have never seen any vaguely credible reproduction.
Best you get is "my friend's LG TV connected to the internet even after changing his WiFI password" vaguely recalled hearsay.
Or the second order retreat-to-motte argument of "well they'll add that to the firmware overnight when ad revenues drop if enough people stop connecting to the internet".
It'd be trivial to prove and yet it has never been proven. I'll give you three guesses why, and the first two don't count.
