Being able to use a radio to know who voted what because of electronic interference emitted by a voting machine is not just a "closed voting machine by a commercial company" problem, but one of pure negligence, ignorance and poor workmanship. If you design a voting machine, you design and test for those requirements.

Wasn't that another product? http://en.wikipedia.org/wiki/Van_Eck_phreaking These hacks are pretty clever.

Either way, you have a point. If anything, the efforts of hackers have upped the requirements of anyone who still has the guts to produce voting machines (and created awareness of the increased costs with their customers) and this is a good thing.
