Vendors must start adding physical on/off switches to devices that can spy on us

For USB devices, you can use a USB off switch like this, which seems like a good idea; but it doesn’t solve the problem for devices with built-in cameras and microphones like laptops and smart phones. And yet there isn’t a hardware off switch for your phone’s camera and microphone, short of turning the device entirely off (but there’s an app to turn the camera off). I think we consumers should demand that webcams, smart phones, smart speakers, and laptop cameras and microphones—and any other devices with cameras and microphones that are connected to the Internet—be built with hardware “off” switches that make it impossible for the camera and microphone to be operated.
