I don't why it should surprise, or bother, anyone that it is running android. Totally reasonable choice. What does it say that it is treated like some sort of gotcha? Were they supposed to build their own AIOS?
because if it's just an android app, you have to wonder why it's not just an app
I mean the question is kind of vaguely legitimate, but regardeless of how it is implemented one could ask why it is not an Android app instead. They thought about it and made other choices, and might not want to publicly list all the reasons that made them choose what they did...
