I think there's a mistake in our assumptions here.
Knowing that not voting now qualifies as a "no" vote means I simply do not vote anymore when I do not want a reset.
I can't speak to how many people do the same, but it would certainly account for the large number of apparent "non-voters". The possibility of this logic informing voting behaviour makes conclusions drawn based on non-voter turnout questionable.
We have the current voting system because the old one was abused. I'm in support of it remaining as is.
Perhaps, for the sake of clarity, we could simply change the language and structure of voting? Vote yes for a reset, with no option to "no" vote.
