Really good q I'm shocked too. Riffing: Without Play Store it's not viable/interesting. Also, it's so. much. work. keeping up with Android releases, even inside Google. Wear and ChromeOS are always a version or two behind, and vast majority of the time, it is two versions. If Google internally wasn't helpful enough to each other, I can't imagine they played nice with Microsoft on this. The broad business war means there's no incentive for VPs to drive it. Technical challenges via CTS* mean there's no incentive for 1-3 steps up the org chart to enable it. The narrow-er business challenge of not having the Play Store is the final nail for any cooperation. I don't think Google is interested in proactively collaborating unless you do CTS. * Android's CTS, compatibility test suite, has to be passed to get the Play Store, and broadly, it is organized around individual device launches, rather than a subsystem than can run on any hardware. (n.b. I worked on Wear then Android at Google, 6 years total)
