By this logic, even your computer has multiple operating systems. The chipset on your motherboard is not pure hardware - there are small cores in there running embedded software that you never see. I am not talking about BIOS, which is another type of firmware, that is visible to the user.
EVERYTHING these days has software. Shipping a software patch is cheaper than a recall. This goes back to the old joke - the mechanical engineer thinks it is an electrical problem, the electrical engineer thinks it is a mechanical problem, but they both agree that it should be fixed in software.
This story reminds me of the Simpsons episode where Kent Brockman breaks a story about the government training people to kill on an industrial scale. "They call it the 'Army', but I have a better name - Killbot Factory".
