I'm not sure if I have enough information to explicitly agree with
your point 8. I think it's highly plausible given what I've seen
(although I don't make a habit of reading source code).

Of course, anywhere you have a free market, you will have trade
secrets*. Maybe you mean to reject trade secrets in voting system
software? If the software is ever disclosed (as DESI's was) any trade
secrets are no longer valid.

* Note that the definition of a trade secret is pretty broad. UTSA
defines "Trade secret" to mean information, including a formula,
pattern, compilation, program, device, method, technique, or process,
that: (i) derives independent economic value, actual or potential,
from not being generally known to, and not being readily ascertainable
by proper means by, other persons who can obtain economic value from
its disclosure or use, and (ii) is the subject of efforts that are
reasonable under the circumstances to maintain its secrecy.

Regardless of the proprietary claims that could be made, would it be
wise from a security perspective to simply disclose the Windows or
BallotStation+GEMS code without some other vetting process that
gussies it up for the sunshine of public scrutiny? Your proposal
below is definitely worth further consideration... instead of taking
code and vetting it for public disclosure, you're advocating replacing
code. That would probably be less work, from what I've seen in
Silicon Valley with companies trying to release existing codebases
under open source licenses (usually, it's tracking down contributors,
etc.; not ensuring that bugs and backdoors are minimized).

Is the idea here that they could keep their trade secrets in their
software, firmware and designs if they replace them with disclosable
versions?

The vendors should be able to opt out of having their code disclosed
at all. Is that in here? -Joe
