I've had two Google Nexus phones and one Android Wear watch, and all three became e-waste before their time purely because Google stopped updating them. In the case of the watch Google actually started sending out "updates" to their own apps that removed functionality from watches with older Android wear, with no possibility to update. It had less features when I threw it away than it had when I bought it.
I'm using Android on my phone not because I want to use a Google made OS, but because it's unfortunately the best option available, since I have other issues with Apple. A Google OS will never be the best option for my real computer, at least I certainly hope so.
I find it slightly hypocritical that the company that deliberately stops updating their own phones and computers based on dates can claim to want to reduce e-waste.
