I agree. Public and non-public derivation in C++ have vastly different meaning. Public derivation means is-a in the technical sense of LSP. Non-public derivation is an implementation detail that expresses has-a in a way that allows easier use or re-exposure of the members of the base class. It has to do with semantics of C++ and has zilch to do with OO design.
