This is a common response but it&#x27;s not addressing the core issue.<p>Bugs and vulnerabilities are discovered every day in the layers that <i>can</i> be independently verified. Your argument extends to every single piece of software everywhere that runs on Intel and AMD microprocessors, for instance. It&#x27;s foolish to say that an OpenSSL instance shouldn&#x27;t be examined because the network interface it communicates over uses a proprietary firmware blob, or runs on Windows, for instance.<p>I agree that the freedom to verify the behavior of (what amounts to) firmware is not one of the Four Freedoms, but there is a non-zero value in being able to find bugs and help the manufacturer improve the product, as well as being able to use that information to inform a purchasing decision. Especially for something which could potentially be considered to provide organizational security.
