I thought the joke was that they had interns write that? I remember an API that would hold onto completion blocks and call them repeatedly instead of just once. They would also accidentally make non backwardly compatible changes to the API.

They didn't care since that API period propelled them to more dominance and growth for awhile. After they shut down the viral channels, the developer ecosystem died...but it had proven its usefulness.

The only issue now is developers don't trust them and they can't get enough developers to build atop them.
