The way facebook is going about this is absolutely the wrong angle.

I understand its their platform, and they can do what they want, but they should live and die like any other payment system. Zynga should choose them because even with the 30% skim, Facebook credits still give Zynga more revenue than other payment systems. This isn't too hard to imagine - Facebook has the ability to integrate credits with their site like no 3rd party provider can.

Instead they come across like cry babies.
