Taiwanese manufacturer of phones and PCs, Acer, planned to hold a joint press conference with China-based Alibaba Group in Shanghai on September 13, Thursday to debut CloudMobile A800, a smartphone which runs on Aliyun operating system developed by Alibaba. But the press conference was canceled before it started. Why the press conference cancelled? To answer the question Alibaba replied that Google threatened to pull its Android support from Acer if Acer pursued Alibaba’s Aliyun operating system. Interesting thing is Acer did not confirm the claim.
