It's not surprising that a small change like this could be enabled with open data, but big changes? There's been plenty of data related to medicare fraud, veteran's admin fraud, etc, but changing big things like that appears to be a no go even though the cost is tremendous in terms of affected lives and money.
Small steps. I think there's a knee-jerk reaction (and anecdotally I've found government organisations to be particularly guilty of this) of taking analysis like this as embarrassing criticism that needs to be rejected, not embraced.
EDIT: Sorry, my point there was - as more things like this happen we should see increased engagement from orgs.
