I'm really suprised the article didn't mention anything about Tizen. For Google, Tizen looks like a big issue. At some point in the future, their biggest hardware seller, Samsung, will start switching all of their devices to running on Tizen and other partners in the Tizen Association (from wikipedia) are Fujitsu, Huawei, Intel, KT, NEC Casio, NTT DoCoMo, Orange, Panasonic, Samsung, SK Telecom, Sprint. Google's going to have to get very aggressive with Fuchsia to compete with Tizen.
Tizen has been 6 years now and there is almost zero percentage of smartphone market and it has become only for Samsung products (look at the association list. Huawei is the only big consumer device company). This would never threat Google.
