Ben isn't running a charity. Exactly. If you have a business model where Dwolla being free is integral to your success, then you're in a very bad place. Always assume you'll have to pay your suppliers/service providers, and keep a healthy margin on top of that to protect yourself from price fluctuations. For a more concrete example, look at Chargify. For a while they were free to anyone under a certain size. Then, they changed their prices and started charging $39/mo (originally it was $99) for the lowest tier. A lot of hackers got burned by that move.
