> Do you want to fly on a plane where the flight control software was maybe overwritten?
I don't understand it. Whoever owns the place can replace any part of it, including computers. So being able to overwrite software doesn't change it. Furthermore, plane computers are not a consumer hardware.
You could make a better example with patched car software.
> The problem is Google and Apple locking down their Operating System, this is not a technical limitation on hardware.
The initial ROM bootloader contains hard-coded signature which prevents you from replacing Apple/Google software.
