Allen's decision was to require those people who care to pony up millions of their own dollars to acquire his personal collection, and keep it running. I'm glad you volunteer your time, but that's a whole other magnitude than purchasing and running a multi-million-dollar business. It's not reasonable to expect volunteers to spring up from nowhere and perform that kind of labor.
Having volunteered for a small not-for profit for nearly a decade now, there's definitely a whole lot of people that just want something with no desire to give back to that community. You really do get what you put in though.
