Spy Handler writes: "In a Microsoft-esque move, Google threatened Acer with banishment from Android if it went ahead with its new cellphone project with Alibaba (China's version of Amazon), using an OS called Aliyun. Acer has remained silent on the issue, but Alibaba reports that they received notification from Google, stating "if the new product launch with Aliyun went ahead, Google would terminate Android product cooperation and related technical authorization with Acer."
Possible reason for Google's upset is that the Aliyun OS, which is not Android, can run Android apps as well as its own." Link to Original Source
