Voting Machine Code

A little naked sectarianism... why does the open source movement get (nearly) all the credit in the struggle to free voting machine code? It's not like we're clamoring for technically superior voting machine code; no, this is an open-and-shut case of "free as in 'free speech'".

Actually, it reminds me more of the old days, when IBM's software was free just because no-one imagined it could have value independent of hardware. Diebold has plenty of patents so why is it worried about letting go of its code?
