> the concept that you shouldn't own your device for safety is so fucked.

That's not it. The concept is "if you choose to install this particular OS on the device you own, then it comes with this particular security model". That's totally fine. If you own your device, you can run Linux on it and you'll have root access.

"Not owning your device" means "not being able to install the OS you want on it". I want to own my device, obviously. But it does not mean that I own the developers of every OS in the world and that they should do whatever I tell them to do, for free.
