> But then many consumers value cost or other things over security, which is why you need all the devices to be able to be updated even after the vendor is gone.
This is only possible if the firmware is replaceable. Along with a practical update mechanism it also requires the possibility to create an update package. That can be achieved by using open source components, but there might be other mechanisms. For example making provisions in case of bankruptcy.
> Then why are you talking about a warranty to begin with?
I was making a comparison with warranty law, which exists to ensure a certain minimum bar for quality and longevity of products. Which is usually desired, therefore legal provisions for updateability of hardware should also be required. Note that a firmware update might well become required within the warranty period.
This is by no means a new concern. IP cams, home routers, robot vacuums, and internet-enabled fridges exist for a long time already. The warranty period was never intended to cover "smart" devices. Maybe forcing an extension of the warranty period for such devices is enough to take care of the problem.
