Since people need someone to provide them one for free if they want to join the p2p network without running hived themselves. I think I understand your point
What if deathwing implemented the feature, ran it for his stuff, and only allowed access to his api from his own website (deathwingsblogservice.com as an example if that helps clear up the question)? The rest of Hive users would have one less public api node to use. Does that make things better in your book?
