In response to Google's claim that Alibaba's operating system, Aliyun, is a forked and incompatible version of Android, the Chinese e-commerce giant said that Google was "just speculating."

Andy Rubin, Google's senior executive stated in a blog post on September 14 that "the Aliyun OS incorporates the Android runtime and was apparently derived from Android." Thus the allegedly forked version of Android cannot be used by electronics producer Acer, which planned to include the system in the brand's new handset.

When asked whether Aliyun incorporates Android elements by technology website CNET, spokesman for Alibaba, John Spelich, said in a statement that "They have no idea and are just speculating. Aliyun is different."

Spelich explained that Aliyun is "built on open-source Linux." It features "our own applications. [It's] designed to run cloud apps designed in our own ecosystem. [It] can run some, but not all, Android apps," he added.

Acer originally planned to hold a press conference on September 13 to introduce its first Aliyun-powered smart phone to the public. But the company had to scrap the conference when it was told by Google that Google would stop providing them with technical support and terminate its other technology licensing with the company if it followed through on its original plans.

Google still insists its claim is legit and said in a statement released on September 14 that "Compatibility is at the heart of the Android ecosystem and ensures a consistent experience for developers, manufacturers, and consumers. Non-compatible versions of Android, like Aliyun, weaken the ecosystem."
