Software licences and who "owns it" in large companies with bespoke service departments must always be a laugh. I had an MD ask me if I had ever heard of some software they were getting billed for (via an all team email). My department used to be part of his thiefdom and everything we used was because of his wants at the time. I quietly went to his desk and pointed at an icon on his own desktop. It was the software in question. No one in any of his divisions used it and we all assumed it was part of the other ones use... and the man who put it there forgot it was him or what it did. The cost was "a lot" a year for years.
