Comes down to making money

“Right now, Google will never admit to this reality. To be honest, I’m not sure most people on the Android team even realize this reality. But at the end of the day, this comes down to making money. Microsoft is currently making more money off of Android than Google is. iOS is providing more mobile revenue when it comes to Google searches. The model is already broken and it runs the risk of cracking wide open unless there’s a product that can keep it together.”
