+  A couple of years ago the Computer Science Club at Bishop's University
+  ran into a problem. Our student run computer lab was running
+  unlicensed copies of a propriety operating system. The computers also
+  had many unlicensed programs installed. It was a big mess. At that
+  time we had to make an ethical decision. We had to decide whether we
+  wanted to continue breaking the law or not. We decided against running
+  software for which we didn't have licenses as it could lead to the lab
+  being closed.
