The last one is a very important paragraph to see the big picture. Without that, my comment might just be an isolated case and fear mongering.

It is important to see although this door lock/car control/whatever problem is new, the underlying thought process is not new. Not having the rights to understand and modify, leading to having to trust what "the cloud" or proprietary software does (especially those that determine your personal security) is a topic that was brought up again and again by the people I mentioned. We will be lost in the details of this particular case of this door lock/crazy customer/picky company otherwise, so I think it is worthy to relay the principles.
