We can talk about what needs fixing, where, and how until everyone is blue in the face. After a point, it becomes clear that nobody is listening. What then?
I won't say it's a moral imperative to be 'deconstructive' when projects get to the point BotN has here, because it's not, but I will say it's better than just lamely walking away to gather around the next thing.
People like BotN and want to see it finished, but DH has made clear that nothing will change his painfully slow and inconsistent development schedule, and that makes people who support him frustrated. Simply throwing frustration away, or bottling it and moving on, are deeply unsatisfying.
Bitching is cathartic, as long as there's cause, and with BotN, there's cause.
