Gerrymandering, preference distortion through no proportional voting systems, Duverger's Law. I mean, I'm glad people are working on the problem-space of democracy, but I'd guess that other issues more greatly effect voter disenfranchisement and apathy.
The problem in 2016 wasn't that anyone "hacked" our election, it's that they hacked our electorate. Turns out that people's opinions are much easier to change than cast ballots.
One problem at a time. This wasn't specifically intended to address disenfranchisement. But commoditizing the infrastructure helps protect against "we don't have enough resources to let all these people in an underserved community vote."
In previous (recent) elections you hear about voting machines sitting in storage or running out of paper ballots. Having a mature and open voting infrastructure allows old, commodity hardware to be used (including paper) instead of expensive, proprietary machines that can go "out of date" and "no longer supported/updated."
