Beyond becoming a "product" with EVs, what worries me just as much is giving up control of the vehicle.
I read an article the other day where the guy was complaining that an over the air update re/moved the defrost windshield button on his Tesla Model 3. It was "there," and then suddenly it wasn't, and he couldn't find it when he needed it. He eventually got the defrost working through voice control.
Imagine if the buttons on your microwave re-arranged themselves (or disappeared entirely) at will. Hell, the other day my PS4 received an update (somehow... I didn't install squat) which moved my custom-installed applications from the main applications section to way the hell down the page. Now the PS4 prioritizes the apps they WANT to prioritize, then they show you a bunch of ads for various crap within those apps, and THEN my apps are accessible below. Of course, I have no control over anything and have to scroll through their bs to get to what I need (and what was previously immediately accessible). I'm just about ready to replace the PS4 with a different device because of this crap.
I know myself well enough that if something along those lines happened with a vehicle I owned, one of two things would follow: selling the vehicle for pennies on the dollar the same day, or a 30 minute sledge-hammer exercise routine followed by a short flight off a tall cliff. I have zero tolerance for bs like that.
When I buy a product, I expect the product to remain as-is until I say otherwise, or until it breaks. Having a third party arbitrarily decide what's best for me is not going to happen. At that point I'd rather call a cab.
If I could pick & choose individual features to be installed over the air, I might be okay with it. But I know that's not sustainable from the vehicle manufacturer's point of view.
Similar kind of crap is slowly sneaking into ICE vehicles, too. Thankfully not to the same extent; at least, not yet.
