But this isn't a secret here. It's just knowledge that hasn't been posted
everywhere. You have to go into the library (be a derived class) to read
it.

If Base made Derived a friend, and Derived advertised this everywhere,
then I think secret would be an appropriate term.

You can always give away what people gave to you. If I tell
you a secret, then nothing can stop you from telling everyone
what the secret is. The only way to prevent that is to refrain
from telling you the secret.

None the less giving away secrets is a breach of trust.
