She doesn’t mention turning off location services. That shit is granular and used as part of the way companies track us.
And even if you turn it off, your location can still be derived by triangulating via cell towers; I’m not sure if that access is widely available or just for law enforcement…. But it I absolutely would not be surprised if it was for sale.
If I were doing this the phone would be turned off when I’m at home, and only used in public or moving in a car; nowhere near my home.
Bout 7 years ago I bought a Vizio tv because it was dumb; all the smart features were via a table it came with that chrome cast to the tv. I was reasonably happy with it.
Then in 2018 they pushed a firmware update that made it smart, and literally made the remote that came with the tv useless; you needed to buy a new one from them to use the tv. And naturally it was always out of stock.
Needless to say I won’t be buying a Vizio ever again. I just do LG tvs now, and don’t let them on the network; all streaming is via Apple TV.
