Hardware has (design) sources, too. And hardware security designs can fail,
too. And they could possibly increase the security with the same measures
open source increases it: "for enough eyes, every bug is shallow" or
something like that. Of course, submitting patches would be a difficult
thing :)

But whether or not that's viable, they don't do it. 

Just an idea about security when I read that. As built-in functionality
gets more complex, it also gets more prone to bugs -- and exploits. We're
talking about almost 100k of firmware IP to protect; that can be a
substantial development effort. Which of course also may invite a
substantial cracking effort.
