That's not what he's saying. He's saying that BMW has already sold the car at a profit with the heating elements built-in, and then are trying to make more profit off of a software patch to enable a feature you technically already own.
If Apple offered you a $1000 iPhone with a camera app installed, and then offered you the same iPhone for $800 but which will not let any camera apps be installed unless you pay them $18/month, does that seem fine to you? They're already making a profit selling at $800, the hardware is identical, it's just a cost-free software change that you are not permitted to make to your own device.
