The CIA likes the idea.
A smart TV that did not need network access to place the code.
Re "suspicious data is going out of our computer"
A person would have to enter the room, access and alter the smart TV, wait for a recoding, a person to collect the data later. No need for the data collected to be networked out later. No network code litter to alter the smart TV, no code litter left in the smart tv later, no changes to any network.
The idea been no network had to be entered to alter the smart TV. No code litter on any network, no need for very strange listening devices in the room.
What new methods could offer is the room change issue. Alter all rooms smart TV's? Just the guests expected to have interesting conversations?
The ability to quickly alter a smart TV in a room that was an unexpected meeting place?
Too late for a human to enter and alter the smart TV, any network code litter might expose the entry attempt, but a new way exists to alter all smart TV's if needed.
The part the CIA liked was the "they can also be turned off " did not work. The smart TV seemed like it was powered off but it was an always on live mic.
