Laws can be updated/modified. If I have a software safety check in a giant combine harvester: if person detected <3m in front of harvester, emergency stop. Farmer finds it annoying so they install a "patch" they found on the Internets that disables it. Now there are two major options legally: * The law states that it's the company who is responsible for this safety feature, therefore the company tries to lock down the hardware/software as much as possible * The law states that modifications null/void certain parts of the warranty & other bits. If I have a warranty on a CPU, isn't it void if I overvolt that CPU to the point it dies? Don't you think it should be? Afaik it's accepted that warranties on cars are void if you do something stupid with them.
