Let's suppose one of the proprietary software components is a special secure bootloader. If Silent Circle disabled that one component, as they would be rightfully allowed to do, the phone is a brick. I should also point out the claim that the baseband was intentionally bricked is unsubstantiated. We don't know if that's actually happening. Or if it's happening, we don't know if it's intentional. The percentage of proprietary software on the phone — be it five percent or fifty — is orthogonal to the point.
