Not really, but I don't think seeing a bunch of code with calls to hidden function would be all that useful.
It is simple enough to distill your approach down into some fictional code that can be easily understood. I do it all the time when I'm posting questions on Stack Overflow and don't want to stick the real code on there.
It might be nice to see some of their production code, but it doesn't really offer any value to them other than being able to fire a shot in an internet war.
