After Google stopped Acer from launching a phone based on Aliyun OS, described non-compatible with build of Android, Google's Andy Rubin, Senior Vice President, Mobile and Digital Content, continued his fight against Alibaba, which coordinated on Aliyun development with Acer, The Verge reported.

Upholding Android interests and responding to Alibaba VP John Spelich's assertion that Aliyun is "not a fork," of Android, Andy Rubin wrote in Google+:

"We agree that the Aliyun OS is not part of the Android ecosystem and you're under no requirement to be compatible. However, the fact is, Aliyun uses the Android runtime, framework and tools. And your app store contains Android apps (including pirated Google apps). So there's really no disputing that Aliyun is based on the Android platform and takes advantage of all the hard work that's gone into that platform by the OHA."

"So if you want to benefit from the Android ecosystem, then make the choice to be compatible. It's easy, free, and we'll even help you out. But if you don't want to be compatible, then don't expect help from OHA members that are all working to support and build a unified Android ecosystem."

Though companies like Amazon can release forked versions of Android, Acer a part of Open Handset Alliance (OHA) can be stopped by Google to prevent fragmentation.

Though Alibaba continued to claim that its OS is built on Linux and not Android, it is not likely to be featured on a handset any time soon, The Verge added.
