Perhaps one of the unanticipated arguments against such an approach might be that Harman Technology Ltd. has managed to rescue the Ilford brand—and the rest of us—by designing and implementing a well thought out business plan to do just that. And that plan is working. For them as well as all of us.
Jumping to a Kickstarter business model could conceivably be incompatible with the continued success of that business plan. And I don't think they, or any of us, would want that.
