As for e-waste, well unlike other major manufacturers every Google phone can be unlocked and you can install any OS you want. So there is no need to discard the hardware after support ends. You just have to bear the support costs yourself. Too expensive? Well, you're the one saying it's not too expensive, so why not start a company to provide extended support for devices like this? Charge $1 per device, that's a healthy profit over the $0.10 you claim it costs.
