You can just stop to the last reason, they don't want to give up ownership back to you.
They would prefer you to throw the device in the bin and buy a new one, preferably from them again.
> they don't want to give up ownership back to you
No, it's simply that your demand is completely unreasonable. You are essentially asking them to adopt an open-source model. That can mean giving up control over its intellectual property and potentially exposing proprietary technology to competitors, especially when some products are valuable precisely because of the software that runs on them.
Edit:
I don't know why it is not allowing me to reply to you.
> No, I'm asking these devices to work like normal computers
What exactly is a "normal computer," and what specific behavior are you expecting?
Can you freely tinker with your motherboard's firmware? Can you modify the Bluetooth or Wi-Fi firmware on your motherboard? Can you modify and independently update the internals of Windows itself? These are all examples of components that are proprietary and subject to limitations, even on what we would consider a "normal computer."
There may be some exceptions to the above, but the same generally applies to mass-produced, commercially distributed devices. They are often locked down for technical, legal, and security reasons, and "unlocking" them is simply not a reasonable expectation in many cases.
