Lucas and Luna unpack a specific failure: Twilio's 2023 deprecation of `twilio-ruby` v5 without a stable migration path. They walk through the timeline — the one-line changelog entry, the six-month window that actually required eight months of refactoring, and the exodus of mid-market Ruby shops to Plivo. They compare Twilio's approach to Stripe's API lifecycle docs and GitHub's sunset header, then drill into a concrete rule: every breaking change needs a `Sunset` HTTP header and an automated migration script, or teams will fork your SDK and never upgrade. One concrete takeaway: developer trust is a balance sheet item, and deprecation is where most API companies accidentally write it down.
