Vendor‑Certificate Single‑Point Failure

Software ecosystems that rely on vendor‑issued developer or signing certificates create single points of operational failure: if a certificate expires, is revoked, or is mis‑managed, large numbers of users and dependent devices can lose functionality instantly (e.g., Logitech’s macOS apps failing when a Developer ID expired). — This matters because consumer device resilience, public‑sector procurement, and national‑security planning increasingly depend on vendor continuity; treating certificate management as a systemic infrastructure risk suggests new regulatory, procurement, and disclosure rules.
