Sony can argue that your license extends to the OS so disabling it to violators is there right. They are not stopping users from using the "hardware"... since thats something physical... they can make it still boot and just display a message that access to the PS3 OS has been revoked.
Disabling the software is completely different from erasing it from the bios. The reason MS disables features when WGA fails but does NOT delete the software from the HD is because they legally cannot do it. Erasing the software, in this case the bios, is modifying the hardware. It could also be considered modifying the hardware in the case of erasing parts or all of the bits stored on a HD. There is a reason why those 30 day trial software and demos don't auto uninstall themselves but just disables themselves or their features. Once the license to use is terminated, then the software loses the right to modify the hardware. This includes the ability to erase itself.
