Those votes did not cost that much voting power, that is a UI problem and will be fixed as tools adjust for HF20. Everyone got dumped to 0% voting power and most people will be 20-30% range right now.
What happened is these UI displays are lazy updated, so they are only updated once you place a vote. This is the same as it was before, but the tools have not adjusted for the HF20 way of displaying it.
I don't disagree with anything you said though.
Ha yeah it's been a journey. When I realized everyone simply went to zero and the updates were simply deprecated it made a lot of sense.
