Don't confuse OCO with licensed software. OCO means that you don't have access to the source even if the program is public domain; licensed means that it only legal to use it if you have a license, even if it provided in source form. I'm aware of several licensed programs that were available *only* in source form.
Copyright is yet another concept, although licensed software is generally copyrighted. -- Shmuel (Seymour J.)
