Acer (OTC:ASIYF) and Alibaba (OTC:ALBCF) just cancelled a smartphone launch featuring the latter's Aliyun OS, and Alibaba is blaming Google (NASDAQ:GOOG). Alibaba, whose OS is Linux-based but can run Android apps, claims Google threatened to "terminate Android cooperation" with Acer if it went ahead with the launch. Though Android is technically open-source, Google wields tight control over what its partners can do with the OS. Baidu and Huawei are two other Chinese firms with mobile OS ambitions.
