In what way does that refute what I said: that Zynga is wholly dependent on Facebook's infrastructure.

This doesnt mean they dont have their own infrastructure - but it is different than an MMO company like SWG/WOW that have their own infrastructure for 100% of the game.

The point made was that Zynga is doing what MMOs do at far lower cost. I said the cost was offset because Facebook foots the bill for the platform on which Zynga depends.
