Good point, this certainly wouldn't work for lobbying. But over 50% of donations still come from wealthy individuals or small donations, so it's a substantial absolute amount of money that still could benefit from moral trade.

I envision this targeting the general public.
I suppose I have a higher credence in a wide audience finding this really appealing. By spending X dollars, you're canceling out X dollars of the other side while simultaneously sending 2*X dollars to an actual charity.
Nobody likes the negative ads in the US - plenty of people donate in order to 'prevent the other side from winning' more than supporting their own candidate.
"the measure Pomodoro-maximization might accidentally become the target, even though the intended target is goal completion."
Nonsense.
