The open-model bargain had a bill

Open models can widen access to capability, lower experimentation costs and create alternatives to a small number of providers. They also move more responsibility to the people who deploy them: security, updates, data provenance and downstream misuse.
Openness is not a single virtue. It is a distribution of power and obligations. The useful question is who can inspect the system, who can repair it and who bears the cost when the model leaves the lab.
