Maybe because it's too risky.

Alibaba wants to do that once, they made a phone[0] (in Chinese) and a operating system called YunOS[1] which forked on Android.

However, that phone was not a success. So eventually they cooperated with phone manufacturers in China to build phones that have YunOS pre-installed rather than build a phone on their own.

After seeing sale counter of those phones[3] (Also in Chinese) though, I don't think they had a lots of fans.
