Copyleft
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
A legal technique that uses copyright law to counter copyright restrictions. It stipulates that you are free to use, modify, and distribute the work, provided that your derivative works also adopt the same free licensing terms.
SCAFFOLDING EFFECT
Reduce cognitive load
Viral freedom. It is not just sharing, but a strategy that forces downstream parties to keep sharing. In ecosystem building, the Copyleft mechanism can prevent giants from "free-riding" on open source achievements and privatizing them, forcing the entire chain to remain open.
Anchor fast decisions
A copyright licensing approach: allows free use, modification, and distribution of the work, but requires derivative works to remain free in the same way (e.g., GPL). Uses copyright as a lever to guarantee freedom.
