Uh-oh, Amazon. Looks like the Federal Communications Commission (FCC) is not playing around when it comes to selling illegal signal jammers. The agency just went public with an investigation into Amazon and other major retailers for allegedly pushing these dodgy devices that can block your cell signal, GPS, and more. Typically advertised as “drone deterrents” or “privacy tools”, these nefarious gadgets are specifically designed to block radio frequencies. This has serious ramifications, cutting off cellular devices and GPS units and impacting emergency communication channels.
