When I copy your secrets, you no longer have secrets - just information that someone else also has. When I copy your code, you still have the code.

before you copy my code I own [the only copy] after you steel/copy it I no longer own [the only copy]

If you steal my secret code, then I no longer have secret code.

The question is whether the secrecy itself has value. I may perceive that it does, and you may conveniently perceive that it doesn't.

It's a dubious mindset, to believe that it's your own call to decide whether something should be of value to someone else.

They are still secrets so long as you dont go punlish them but use them yourself

Code is worthless on it's own.
