Not only did I opt out, verbally by calling OnStar from the car, I then removed the cell antenna (SparkEV), which works well in the rural areas where I live, not sure about a cellular-dense location, they can probably track pings now and then. So, if I get around to it I will look into disconnecting the cell module under the passenger seat.
Sadly, most new cars are Internet connected nowadays, not just EV.
In fact, GM got caught selling customers data from their ICE cars (OnStar connected).
