Hard to say. My experience with people in general is that they’ll keep going even if things aren’t great, but they’ll get upset. And eventually things will come to a head and there’s a major change in a short period of time. This being a somewhat democratic platform, I would bet that we’ll have that sort of trajectory.
As for donations, it’s just very hard to get people to donate enough and often enough to support this kind of thing. Think of the regular donation appeals on public radio, or Wikipedia, or even The Guardian. They have a whole organization and system built around soliciting donations, and even then they are always operating on a shoestring. How often do you donate? How often do your friends and family?
