Huh? Zynga's apps only depend on Facebook for advertising in users' streams. This is no different than Google refusing to show a company's ads.
This is what happens when you depend on anyone for anything.

As a platform owner, it must suck that people are making more money off your platform than you. So you are tempted to co-op other people's revenue stream as your own.
Now, this isn't the same type of garden as AOL in the day. It's more open, but make no mistake, Facebook controls the user, not Zynga. Because of this, Zynga has more risk than another web-based game company would be. At the same time though, Zynga has gained incredibly from the relationship.
But, if Zynga wants to keep the users coming, it needs to maintain that Facebook relationship.
A more appropriate analogy would be if Google had paid inclusion of advertisement directly in search results, rather than on the side. In that case, it would be fair for Google to be extremely judicious about those ads.
