Kate Moussouris: Fable 5 Export Controls Harm US Cyber Defense

Luta Security·medium signal

Luta Security founder Kate Moussouris — a foundational figure in coordinated vulnerability disclosure — argues the government directive restricting Fable 5/Mythos 5 actively undermines defensive security, because barring a model from fixing vulnerabilities removes a tool defenders rely on more than attackers. It is a credentialed expert counter-argument to the export-control rationale rather than more coverage of the shutdown itself. The defensive-security framing is a distinct, named-source angle on the policy fight.
