> Why do I trust my WiFi cards disable pin, but not the "soft button" on my laptop that triggers it via the OS? I get that there is more software when it goes through the OS, but I trust that a whole lot more than the firmware on the WiFi card. When using a physical kill switch you have to trust the hardware. You don't have to trust the firmware or operating system, as a physical kill switch usually disables the power lines to the device. That's something a remote attacker can't circumvent.
