With all due respect to Wikipedia for what it is, I believe their success is partly because of the 'altruistic' nature of their model. Sure, they should seek donations from huge companies like Google - which make tons of money off of their data - for the services they provide, but I feel like locking down the 'better' api to the public is not the way to go about it. It's just too often that a commercial offering just disincentives bettering the 'free' product.
Wikipedia as the product of a public good foundation should be just that; by the public, for the public, and accessible to the public (including all access methods and API's).
