LG smart TVs caught logging audio with screen off and snooping on local devices

Not that simple for her, she likes some of the features it offers. For example, using the youtube app on your phone to control videos on the TV. I've blocked most unrelated domains tho, including the update domains so I'm not being surprised by a random update that bypasses everything I've set up.
Once I got a bit of time, I play on building a pi box that works similarly to what she's expecting.
