You don't own your device, you are just licensing it. When you pay for a device you are only paying a license to use the device, since you need a firmware to run the device and the firmware is licensed to you without any ownership transfer. Your device does what the firmware allow it to do, therefore you are only allowed to do what the real owner of the firmware wants you to do.
