True, but the guy in the suit is influenced by people other than salesmen as well, most of all by hype. I remember when Java came onto the scene. Within a few years everyone was busy porting everything to Java. If something like that happens again, Oracle (and others) will have to write down billions.
If I were Oracle, I would not want to provoke someone like Google to drop Java and really throw its weight behind a different mainstream applications platform. Oracle is playing a dangerous game right now. No army of salespeople will save them if and when the tide turns. These things are non linear.
