Based on this security concern, I've compiled an exhaustive list of things people should look for when opening up a smart TV to assess its suitability as a spying device:
1. battery
In an age where people typically carry smart cell phones everywhere, there's only one question for people with privacy concerns about smart TVs: If I'm concerned about state actors hearing my conversation, is it sufficient to unplug the smart TV?
I searched for the word "battery" and didn't find it in the article. That's not useful. I guess if I ever need to have a conversation where I'm concerned about government spying, I'll just put all the other microphone-equipped devices in the room with the smart TV and go talk somewhere out of earshot of it.
