You did not depend on the manufacturer to do that maintenance. The manufacturer could have even gone out of business and you could still fix or find someone to fix your car.
You however depend on the original developer to click that build button because proprietary software. If it was FLOSS, you could.
But don't worry, thanks to DRMed parts you won't be able to fix anything on your car either (or phone, or any other smart device) without the involvement of the original manufacturer. Ain't property wonderful when the manufacturers intelectual property has precedence over your physical property?
I think you misunderstood the analogy - the app is the car, not the parts. Once you correct that it’s easy to understand why the rest of your message doesn’t make sense.
