What happened
In 1996, id Software released a $10 Quake shareware CD that locked full versions of all their games behind an encryption scheme unlocked via phone payment. The encryption was cracked within 39 days, leaving the developer with 150,000 unsellable discs.
Why it matters
A cautionary tale about DRM and payment-gated content: if your unlock mechanism is the sole revenue path for a physical product, a single cryptographic flaw can wipe out your inventory value overnight. Not actionable for modern builders but a useful historical reference for anyone designing license or access-control systems.
Discussion angle
What modern equivalents exist today — SaaS license keys or agent API tokens that, if broken, instantly devalue a shipped product — and how do current builders mitigate that risk compared to id Software's 1996 approach?
