   Perhaps add a comment on why we don’t want to copy CNetMessage objects.

   This is absolutely fine. I would have gone for something like “For performance reasons, once we’ve deserialized the bytes into a CNetMessage, we avoid re-allocating and copying the message as we pass it up the stack for processing. Delete the copy ctor/assignment to avoid accidentally introducing a copy operation.”, which is more-or-less the same as what you came up with.
