All those users just lost faith in yet another service, and all these guys are doing is saying "Hey, we failed you as a SAAS vendor, but we made $100 million, so lube up and try GREE because they need to [overcharge you voraciously to] recoup their investment.
You'd think the geniuses in the game industry could put their collective [self acclaimed] intellects together to come up with a platform agnostic approach to these common issues, and open source it for the betterment of the customer.
Oh, yeah... the... customer. Oops.
>>>>>>>>>>> UPDATE <<<<<<<<<<
OOH.. and it gets better... From GREE's agreement, paraphrased:
ARTICLE 5: Virtual Currency; Revenue Sharing
We've created our own currencies, not unlike BitCoin, called J-Coins and G-Coins. We reserve the right to change the ratios to capture more revenue, but right now you should just trust us that we're being honest.
Customers will pay US, not you. We'll tell you how much they spent of that money with you, and then pay you what we think is fair, in our sole discretion.
Oh yeah, to further confuse the customer, you can't call YOUR currency anything like ours, and we get to decide what you call it, and if you don't change it, we don't have to pay you.
