Binary blobs are obsolete.
Besides all the secret services around the world, just think of SMM. Or TR069 to configure your router remotely. There are a lot of dangerous things in the firmware, some maybe once built with a good intention but now prone to security holes and generally dangerous to the user and system. Open Firmware is more trustworthy in the long term, and once grown also more stable.
Stop TCPA, stupid software patents and corrupt politicians!
