A small group of volunteers from Israel’s tech sector is working tirelessly to remove content it says doesn’t belong on platforms like Facebook and TikTok, tapping personal connections at those and other Big Tech companies to have posts deleted outside official channels, the project’s founder told The Intercept.

Amazon Sidewalk is a new feature that enables Amazon devices like Rings and Echos to perform a similar function, but instead with neighboring wifi networks. Sidewalk empowers these devices to connect to other Sidewalk-enabled hardware at long ranges using nearby wifi and bluetooth signals. Just as the hot tub works further away from your neighbor’s home by plugging into yours, the point of Sidewalk is to extend the distance at which the devices work by plugging into nearby wifi networks away from the ‘home’ network.
