"Audi car keeps nagging car owners who decided against premium features when they bought their car."

Would be appropriate too, I think. It is one thing to just not include a certain feature, but it is another thing to still include a button that only has the function to remind you of a possible paid upgrade.

People thought that they bought a car, but they also bought a relation with a company. Like people who buy a smart TV and think they bought just a TV set. Actually they bought a TV set and a relationship with a TV producer who now keeps sucking up their data and shows ads on top of the programs that they intended to watch. How should I call this? Smartphoneification of everything? Is this a good thing?
