It restricts ideas. Look at the comparison between canon by corporations and myths from storytellers. The canon restricts all established ideas as "facts," and any new ideas must conform and "fit" into what's been established. Storytellers, on the other hand, tell tales no matter whether or not they contradict; hence why multiple versions of the same legend may contradict each other. Hope that helps ~
