Game theory applies here. There will always be one journalist without any moral qualms that’ll stay, betting on everyone else leaving, and making a scoop.
Rely on traditional trade craft. A bouncing bevy of brothel, escort service, deepthroats; historically and dramatized, is a staid and proven primary source.
That's some bar moving. In one case we're saying that even if you report garbage, your competitors are going to occupy the niche without you, therefore something something game theory.
But in this other case, well there's just no value to reporting garbage.
Have you ever seen a White House press conference? People scream their questions in the hope of being the loudest, because the president only answers a few. If most of the competition for question time leaves, there’s more time for you to get that juicy soundbite you’re after.
Have you seen a white house press conference lately? It's all just the same talking points. Everyone gets to report on the sound bites. You're choosing to describe these things as if the game theoretics are qualitatively different. Your description is doing more of the work than the game theory.
