Neither of these points are true. Other manufacturers like Toyota are getting into the "features as a service" game with things like keyless entry.
On the surveillance point, I worked for an auto software company that partnered with a big auto manufacturer on a feature. We were granted access to an API that could geolocate any vehicle made by this company in real-time given its VIN. I volunteered my car's VIN to test with (I drove the same make as the company we partnered with) and confirmed that the API returned real-time location data on my 2019 vehicle. If you own a car that was built in the last 10 years, you are more than likely emitting your location to an internal service maintained by the manufacturer.
