Facebook Changing Zynga Terms Fuels Gaming Clash Concerns
This article is for subscribers only.
Facebook Inc. and Zynga Inc. loosened terms of a longstanding alliance, giving themselves greater leeway to pursue social gaming independently and heightening concern that the companies will one day be rivals.
Zynga, which makes most of its money by selling virtual goods in games played on Facebook, will no longer be required to use Facebook as the login for game users, according to the terms of the new contract. Zynga can also elect not to use Facebook Payments as the way for users to make purchases, and it can opt not to display ads served by Facebook. Facebook will also be able to develop its own games.
