I agree that the DHF is a cunning approach, but the problem can be in the details. Also, DHF does not guarantee funding for the whole project duration because one option is that it has to reach a certain limit, which someone, a whale, can quickly melt down if they don't like your project. On the other hand, as @mypathtofire mentioned, some who have reached that limit are just living on their laurels. It seems to me that we still have a lot to learn in this decentralized world.
