Have you checked the last Google Io?
They don't hide that they collect data.
Android is still open.
You can't expect Google to just give you a android distribution without their stuff for free just because.
You still can use it.
They have a mode in Chrome called "incognito mode" that, to the average person, strongly implies it doesn't collect data, yet of course it does.
It says what it does right there when you open it, and collecting data _and sending it to google_ would be pretty damn weird in incognito mode.
You're not invisible to websites, ISPs, ... and it says so right on the page.
