Wait until you hear about my ISPs that throttle my "unlimited" "gigabit" connection whenever they want, or my mobile provider that auto-compresses HD video on all platforms, or my local restaurant that just shrinkflationed how much food you get for the same price, or my gym where 'small group' personal trainer sessions went from 5 to 25 people per session, or this fruit basket company that went from 25% honeydew to 75% honeydew, or the literal origin of "your mileage may vary".

Taken to its conclusion, Anthropic could silently replace Opus with Haiku quality internals and you'd have no recourse. If that sounds absurd, that's exactly where the legal argument lives. Mandatory consumer protection provisions like on misleading omissions cannot be waived by clicking "I agree."
