Amazon will soon share your internet with neighbors (US only)

If you use Alexa or Echo devices, Amazon's newest experiment gives you a week to opt-out before the e-commerce giant hands a slice of your network bandwidth to your neighborhood. Amazon's Sidewalk project would help devices "get connected and stay connected" (using an unknown neighbor's internet) even when they are outside host Wi-Fi network's reach. Similarly, your neighbors' out-of-range devices will use your network.
