A conversation with Andrew "bunnie" Huang about firmware, the code that runs underneath your operating system, closest to the hardware, with more control over your machine than anything else on it, and why almost none of it is open.
We start with the basic irony: the most powerful layer in the whole stack is the most locked down. bunnie explains why. A lot of it isn't sinister. It's companies that lost their own source code, libraries they can't legally open, code they're ashamed of, and debugging hooks that became backdoors. We talk about how a debug feature turns into a security hole, why a network card has near-total access to your memory, and why fixing any of this would mean a vendor starting over from scratch at a cost of millions.
From there we get into whether you could sign your own keys into your firmware, why open-source security silicon is making the old excuses weaker, and why appliances should ship with open firmware that's then permanently locked. A dishwasher doesn't need internet access or updates. That leads into the right-to-repair fight: why your dehumidifier comes with Wi-Fi it doesn't need, how subsidized hardware and repair monopolies work, and Louis Rossmann's campaign against all of it.
