re: the example you give about VP Biden announcing secret cyber attacks against Russia during an NBC News interview, it isnt necessarily a waste to "burn processing cycles" keeping up with such news, when you consider that observing propaganda in action can itself provide information about "what" exactly the "powers that be" want people to believe, leading to further examination of "why".

it is similar to reading financial news or watching CNBC with the mindset of reading between the lines, wondering who and why is interested in propagating such stories.
