For smartwatches, it’s Apple against the world. Per recent numbers from CounterPoint, the Apple Watch commanded more than one-third of global shipments in Q1. Samsung/Tizen’s own market share is a distant — but respectable — second place, with 8%. With Google’s Wear OS at fifth place at just under 4%, it’s easy to see both companies — utterly dominant in other categories — are itching for competitive advantages.

For Google, the answer is two-fold. First, the Fitbit acquisition effectively doubles its existing market. Convincing Samsung to return to Wear OS after a long time in the Tizen woods. For Samsung, a return to the Google operating system made sense from the standpoint of developer access — and the resulting apps. And hey, if it means Google gets to deal with the underlying support issues, that’s all the better.
