Google it seems will remove apps that use 3rd party payment options for in-app purchase (like ZooZ or Paypal). Only payment via google's payment option will be allowed.
I believe that is what Cor is trying to highlight.
I think he is asking what with the developers who can publish only a free applications , and if you want paid app how to receive the money if your country is not supported by google checkout?
You are right, Google is working on this and it is in the news. It seems in app things like virtual currency etc. need to go through in app billing (Google seems to remove apps. from certain developers that don't comply) but goods can go through another one like for example Zooz.
I think we will see the same policy as Apple in the end.
