Our reading
An editorial interpretation.
The speaker measures a secret's value by whether it can be repeated, neatly contradicting the usual purpose of secrecy. The result is a compact joke about wanting information mainly for the pleasure of passing it on. Calling it a Fishism gives this questionable rule the shape of a personal maxim.
