Amazon's Sidewalk program has launched. Here's how to opt out.

Amazon launched new technology this week to share internet among its customers, which the company says will improve the performance of some devices. But it also has some privacy advocates concerned.

If you own certain Alexa-enabled Echo devices or some Ring camera models, Amazon will be able to use part of your home's Wi-Fi to create a new network called Amazon Sidewalk. "Amazon Sidewalk is an ad-hoc mesh network that takes advantage of your Amazon smart devices," said CBS News tech reporter Dan Patterson. The new service takes a small sliver of WiFi at homes with certain Amazon products and uses it to create a shared network within neighborhoods. The so-called Sidewalk Bridge allows devices with spotty Wi-Fi to stay connected.
