I have my doubts. I suspect that Nvidia have made mistakes.

Anyway, situations like the one you describe are one to be solved by legislation requiring certain devices be sold as open devices that put power in the hands of the owner.

my nintendo switch is "rootable" by shorting two pins in the controller interface, with a previously set up SD card inserted with the homebrew bootloader.

My PS3 and PS4 were both jailbroken/rooted. I don't remember the ps3 routine, but the PS4 was loading the "system -> help" page while connected to a ESP32 wifi AP running a simple web server that replied to requests with the jailbreak for PS4.

I give it about a year, especially if nintendo has to change the specs or otherwise tampers with customer expectations. there's bound to be some way to reload firmware on a "dead" device without pulling chips, and that's all it takes.
