This would be an outrageous, almost impossible situation in car "ownership", surely resulting in class action - "I want to use my car's trunk!". But, in computers/phones it's begrudgingly accepted or sometimes even argued for.
I'm not grateful to the manufacturer that I've been graciously allowed to use all of the car I bought, and only after a team of amazing volunteer locksmiths worked day and night adapting the trunk so anyone can use it.
Sure, buy a different car, right? But this also happens to be the safest and easiest one available to drive. And this isn't because the trunk is locked. The owner could equally lock it themselves, just like the rest of the car.
Would be great to use it like any other car, and chuck that potential spyware I'm paying extra in gas to haul around with me. Not thankful that the manufacturer didn't put a stronger lock on it. Actually, I've contempt for them.
