"This to me means that spyware might collect data at any time of the day via my TV, but it does not send it when the TV is off. At least when the TV is turned off, the CIA, or any other agent, cannot listen into my living room live via this TV."
This comment is irrelevent. If you read the wiki, it states that CIA infected TVs are put into "fake off" mode, which means screen/sound is black, but tv is on.
The traffic analysis is not based on the mode of the TV, it only checks if there are any wifi packets coming from the TV. My results suggest that there were zero packets coming from the TV when nobody in the house was watching TV.
